I wanted to get one of these gsp's today from walmart, and there were some that looked sort of black. Is that a bad thing? And also how small of a tank can you have that the fish is actually gonna LIVE in? The biggest one they had was 10 gallons but we almost got a 3 gallon one. So far from what I've read on here it needs to be 10g or bigger. But I'm not too sure. Also where do you get the shrimp and stuff from? I'm really glad I came on here and got info...if I hadn't I might have killed a poor puffer! Please help if you know any answers to my questions:) thank you:)

    These fish will never live through a cycling process... They are very susceptible to ammonia poisoning... why don't you just go to home depot and buy the pure ammonia to cycle your tank the fishless cycle way. Its cheaper then buying fish to do it for yah and then causing permanent damage to your fish.

    Won't be long they eat guppies, I just fed mine smaller guppies they bite them in half and then consume.

    Better watch out with that betta in there, he might die from stress put on by the betta.
  • zach - 2010-06-27
    Be careful with keeping him with your betta he might try and eat it. My 2 puffers ate all the fins right off my betta he is ok but I had to move him to a different tank.

    Do you give your gsp live or dead ghost shrimp?

Okay so I have had puffer fish in the past but died because they got sucked up the filter, so I bought a filter cover. Then I got 2 more puffer fish, babies, and they got along fine. SO I got 1 more puffer, a sucker fish, and 2 mollies. The next morning I came back and my sucker fish had died. SO I took it back to walmart and they refunded my money, when I got back from walmart my 2 baby puffer fish and my white molly were dead, and at this point I was really freaking out. So I took them back to walmart, and I told them the story and they said "maybe your water is off". So the next day I come back from school and my orange molly was HALF EATEN! So now I realize my puffer fish was doing this. So now there was no more fish to eat I couldn't separate them because it was too late. So that night I was feeding my puffer fish (even though he didn't need it ) and there was a new born baby molly! What is going on! And how do I keep my puffer from eating it? Please please help!
p.s I have decided to name my puffer fish Jeffrey Dahmer

    Sorry but that molly is as good as dead too, unless you put him in a separate tank asap. Puffers like live food especially snails. Food for thought.

Can a spotted green puffer (1) live comfortable in a ten gallon tank?

I bought 2 of these fish last week, how often should I add salt to the tank? I plan on filtering half of the water out to clean it at least twice a month should I just re-salt it then?

Ariel Mohan - 2010-04-01
I've read a few other comments and now im concerned my fish is going to die. See I got a fish like two hours ago rinsed the bowl gravel and plant off not with soap I did all that I was supposed to with that. I'm concerned that people said he won't live long in freshwater? Does that mean like days or years? Also he's in a one gallon fish bowl. See my reasoning for this is he's a little smaller than my pinker so when he grows I'll have more money to buy a bigger tank I thought this one would do since he is the only one. I was planning on buying something else to put in the fish bowl but I'm concerned about the salt thing and the flake thing. I live in kansas in a very very country area the closest thing is a walmart. Am I not able to take care of this fish? :(

    That is why I recommend doing research first on the fish you want then getting the tank first and food. But as for the salt thing you can slowly change them to brackish water but get a bigger tank first before changing it on him and chances are he's in better hands with you then wal-mart and they need a water temp of 72-82degrees Fahrenheit if you need further help email me at

    Well I've been reading online, researching about these fishes so I could take care of my own two puffers. They say that each puffer fish should have a filter that is capable of filtering 30 gallons of water for one puffer, because they produce a lot of waste. They also need the tank ph level between 7.5 and 8.5 which would help if you got an excellent filter system. I have a 55 gallon tank and have a 70 gallon aqua clear filter and a ren star canister filter for a 70gallon tank. That's a total of 140 gallons it would be cleaning although I only have a 55 gallon tank. The reason is I have 16 cichlids with the two puffers. The extra gallons of filtration really helps for the large amount of fish I have in my tank. Also the best water temperature for the puffers is 78 to 82 degrees, so you'll need a water heater. Make sure your puffers are feed snails and small crabs every now and then to help file their teeth down because they will grow until the fish eventually won't be able to close its mouth to eat. Also the puffers live best in brackish or salt water conditions. I was advised that they won't live too long in fresh water. Only time will tell, but it's a gamble you'll be taking on your little puffers life. My tank set up is brackish right now. Well iIhope this helps you out. :)

    If you are talking about a gsp (green spotted puffer) turn around get back to that wal-mart and buy the biggest tank they have and some marine salt ( aquarium salt will do in a pinch but don't us any food grade salt) he WILL NOT live more than a short time (weeks at best) in that bowl. They are amazing fish and really fun to watch. Oh and they can grow pretty fast, I have had mine about 2 months and he has doubled in size!
  • Anna - 2010-06-15
    I put mine in freshwater with a little bit of water conditioner and a little bit of aquarium salt and he's doing fine:) I also bought all of this stuff at walmart... hope this helps!
  • pufferlvr - 2010-06-15
    You should not use any type of chemicals in your bowl, while you washed it out the contaminants can still hurt your fish. Also, a one gallon will kill your fish in less than a week. Feed your puffer brine shrimp and make sure you have a 1.012 minimum salt need marine salt. Your puffer will most likely not eat flakes. Finally do whatever you can to get your Walmart to stop selling these puffers if you do not think your two has what they need. These fish are difficult to take care of and need specific attention.

    You can try to find a larger cheap fish tank on 1 gallon is too small for puffer. My puffer eat flakes and shrimps and blood worms.

    I bought my puffer fish in walmart the only place I could find them. I have 2 in a 5 gallon tank. I had them in a fresh water and then I add some marine salt 1/2 of a small packet of salt, I give them frozen shrimps 1 a day, and when I am away for few days I put the white 3 day food. I have them for 3 month approx. and they are fine so far. They come to the surface every time I get close to their tank. I thnk even if the place that we buy the fish we should read about them before we buy them, regardless of the place we buy them and have the tank ready for them, they are adorable. I had some die many years ago then I was told they could be with 5 different fish in a 10 gallon tank. Now I have 2 of them happy in a 5 gallon. I do clean the water 2 times a month.

My son saw the puffers at Walmart and had to have them. We bought a 10 gallon aquarium and after 1 week bought 2 puffers, 2 gouramis, and a corydora. The gouramis died after about 2 weeks of some fin disease. The puffers and corydora seem to be doing ok after nearly a month. One puffer "Brian" is very aggressive and eats whatever he can get. The other "James" was very shy and not eating at first but is now doing well. I started feeding James by putting food in a forceps and placing it right in front of him. The forceps kept Brian away at first and gave James some confidence. Now they both go after the food on the forceps. We'll see what happens. I am going to start the frequent water changes since it sounds like my tank is small for 2 puffers. Do fake plants do as well as real plants for the puffers to hide? I'm afraid to add real plants.....algae

    I would pull the cory out of the tank. Cories are very sensitive to salt and if you are adding aquarium salt to the puffer tank it will kill your cory. Cories are also best kept in schools of at least three, preferably six.

    Real plants are always good in any tank. They help with water maintenance and shouldn't contribute to algae. Most come with pond snails already on them, which your puffers will love! :)
  • pufferlvr - 2010-06-15
    2 puffers need at least a 20 gallon tank...they should have 50. You can put in real plants because it is good to have objects in the tank that will break the puffers' line of sight. Also...they need marine salt appx 1.012-1.015 and as they get older they will need even they shouldn't be mixed with freshwater fish.

I have two puffers (Hindenburg and Bloat) and they have been eating all my other smaller fish in the tank. Is there anything that I can feed them so they won't eat my little fish?

    They are typically suppose to be in there own tank, we had to seperate ours from our other fish because they were doing the same to ours. They have also killed my dragon goby(drangonfish) by nipping all of her fins off. I have 4 of them. They were put into their own tank and are feed special foods, like feeder fish and frozen blood worms, and of course they need snails to eat!
  • Laura - 2010-03-10
    Jess, puffers are very aggresive fish. Keep them with their own kind only. Also, feed them frozen blood worms and half-shelled frozen clams. They need to nibble on the clam shells to keep their teeth trimmed, otherwise, they won't be able to eventually eat as the teeth grow and not allow them to consume their food.
  • pufferlvr - 2010-06-15
    Make sure they have enough least 20 gallons and you need plenty of plants/rocks to break the line of sight and give your other fish places to hide.
Shannon - 2010-02-19
I just bought a young green spotted puffer fish and when I brought him he was in a 5 gallon tank with other fish of his kind and other kinds. I also bought 2 fancy tailed guppies being he was with other fish in a 5 gallon, I thought it would be fine. I put them together in a 10 gallon tank and the water was 75 degrees. I wake up this morning and my guppies are dead and the puffer fish alive, the guppies have no bite marks on them or anything so I dont think they were killed. How could the guppies have died?

    Dear Shannon,

    Puffers are very aggresive and usually kill other fish. Only keep puffers with puffers. be sure and feed them frozen blood worms, krill, brine shrimp and frozen half-shelled clams - which they need to keep their teeth trimmed by nibbling on the shell. If they can't keep their teeth short, they won't eat.
  • pufferlvr - 2010-06-15
    If you have multiple puffers and other fish you need 50 gallons of water. Try at least a 20 gallon tank. I can tell you 10 gallons is not enough. Sorry about your guppies but I know nothing about them. I do know that your puffers need more water or they will die too.
