    Maybe if you're tank is large enough, and you add the Electric Blue Jack Dempsey as a young juvenile they would be okay. But in general they are usually a bit too aggressive for the Blood Parrot. The Blood Parrot page under the Social Behaviors section has some companion suggestions if you want to check that out.

    You can put 10 or more in the fish tank don't be scared.

    Most likely 6 or so Kribensis will get along fine in a 55 gallon tank. They are peaceful and generally non-aggressive community fish. You may want to provide plenty of plants and other hiding places for them. Also, these fish can reach 4' when full grown so you will want to make sure that you have enough room for them to grow comfortably.

    I have 2 pairs of kribs in 1 of my 55s, they're constantly fighting (and both sets have their own caves) and they generally don't let any of the other fish in the bottom half of the tank. I would stick to 1 pair, 1 cave, and a 10-20 gallon tank. I wouldn't describe them as peaceful community fish - quite the opposite. They are however VERY interesting fish.

I am setting up a 40 gallon aquarium in a Church Nursery. It will be seen on both front and back. Any thoughts on how to hide the cords and filter system. Also I will need an auto-feed system because I will only be able to physically be there a couple of days a week.

    You can use a sump style and keep heater in there.

I have a 10 gallon freshwater tank that I bought and waited a week before adding fish. The fish would die within hours every time. I was told to wait and cycle. I cycled and waited for a couple months. I brought some water in to have it tested and everything was good except the ph was 7.5 and was told to bring it down to 7. I bought the buffer they recommended and 4 variable Platy fish. Brought everything home put some of the tank water in the bag for conditioning. Waited 30 minutes and placed the fish in the tank. Added some food which they ate fast and then they swam around really really fast then died a couple hours later. Any thoughts? I pulled out all the ornaments because of the algae.

    How is you amonia level?
  • person - 2012-07-11
    If there is algae growth then you problably need to do a water change and don't put any tank water in the bag when you bring them home first let the bag float at the surface of the water for 20 minutes then just pour the bag with the fish in the fish tank carefully, it worked for me

I am setting up a brand new five gallon aquarium. I have been cycling it for about three weeks now, but I still get ammonia readings (as tested with the API master test kit) of about 4ppm, zero nitrites, zero nitrates. It is as though the bacteria I need aren't there. What am I doing wrong? I have been using surfactant-, perfume- and dye-free ammonia, have the heater running at a constant temperature and the filter running 24/7. The water looks fine, and there are no fish in it yet. I want to give my son his fish in three more weeks, but right now it looks like the bacteria isn't coming in. Any tips?

    Cycling without fish in the tank the levels will get to about 4 then will eventually drop.  Slowly adding fish will speed this up.  Mollies are good for this.
  • Stephanie - 2013-01-09
    Thanks Jeremy! I ended up buying live bacteria online. That finally seemed to do the trick! Now, one and a half weeks after introducing the bacteria, they are eating ammonia like there is no tomorrow, and the nitrite levels, after spiking initially for a few days, stay low to zero now.

Hi I need a bit of help. I have two Blackkmoor Fish that are just over a week old. One tends to spend its time lying upside down by the filter and the other one tends to hide in the ornament. They do not appear to have any diseases on them and feed quite well. The do swim around for a while but always tend to go back to their habits. We did have two orandas originally with live plants and they shredded the plants to death so it kept blocking up the filter, but I think we overfed them and they met their end. We reset the tank up with no live plants for over 3 days and then put the Blackmoors in. i do not want to lose these as it is a bit distressing for my 6 year old to go through it again. I have not done a water change yet.

    It could just be over fed.  Maybe constipated?  Try a frozen pea.  Check water conditions.

    no, fresh pea

It has been my experience that cold and large water changes wash the color off the fish as this puts some fish in more stress than others. Since fish keeping is all about the quality of the water. I do several water changes, 3 or 4 per week. I put back the water volume I took out, but I make sure the temperature is as close if not right on as the temperature as what is in the tank. Also, I do my water changes as fast as possible, to reduce the stress put on the fish. Hope this helps.

    That is alot of water changes! How do you manage the temp so it is close to the tanks temp?
  • SUSIE - 2011-12-18
    A ONCE A MONTH WATER CHANGE IS ALL THAT IS SUGGESTED TO REPLACE TRACE ELEMENTS. I CAN'T IMAGINE WHY ANYONE WOULD NEED 3-4 A WEEK! NOT ONLY WOULD THAT STRESS THE FISH BUT TAKE SOME ENJOYMENT OUT FOR THE OWNER WITH ALL THAT UNNECESSARY WORK. I 'VACCUUM' AND 'REPLACE' ONCE OR TWICE A MONTH AND THEY STAY CRYSTAL CLEAR.
  • Kayl - 2012-01-31
    Crystal clear and clean are not the same thing. The water can be crystal clear and toxic with ammonia , nitrites, and nitrates. While 3 or 4 times a week may be more than strictly necessary, once a month is often not enough depending on stocking levels. Replacing trace elements is not the only reason for water changes--removing nitrate build up is the much bigger concern. Higher bio loads will give you a faster nitrate build up, necessitating more frequent water changes.
  • Kevin - 2012-02-04
    I am very interested in knowing why you need so many water changes per week. This is most likley more stressfull on your fish than the recommended water change times. Just curious.....never have I heard of so many water changes so often. Have a great day.
  • satish - 2012-03-31
    Dear kevin,
    Water changes are good for fishes and plants.
    I know an aquarium owner who has a degree in fisheries, who carries out 100% water change every day. Only thing you need to worry is that the water is free of chlorine and the temperature is the same.
    This guy follows flow thru principle and still i never saw a single dead fish in his shop.
  • Chloe - 2012-06-01
    I do a 15% water change once a week and my fish is fine and loving life!!! We check the water after every change, and it's always perfect! Happy fish keeping!!!

    i just cleaned my 30 gal tank and in 2 day it clouds up what's with that? I HAVE HAD A FISH TANK FOR A LONG TIME AND IT HAS NEVER DONE THIS.

I have a question we recently had to restart our tank due to bringing home a sick fish and it getting the rest of our fish sick. Petco recommends starting with one fish and adding one a week, does this sound right or a little to aggressive or quick? Also we started with a pearlscale goldfish which are slower moving fish, I read online it's not a good idea to add common goldfish or shubinkins because they are much faster and at eating time they get most of the food and the slower fish do not get enough to eat. I notice on here there are some that have slower and faster fish combined, do those who do have any problems with the slower fish getting enough to eat?

one of my my fish just died. I think it was the floss my brother use to tie the plastic plants. Is it possible ?

  • Charlie Roche - 2011-12-29
    Anything is possible but I wouln't have thought floss would do it. Some flosses are coated and I don't even think the fish would have tried to eat it but again anything is possible.
  • Jeremy Roche - 2012-05-10
    What kind of fish? Did it eat the floss?

    Try adding a bottom feeder or alge eater such as the placacus. It will eat all the excessive waste a gold fish produces. (gold fish can be a very 'nasty tank fish'... My Family has kept fish tanks for years and currently we have a goldfish tank. It's about 40 gal with a side tank filter system with 3 7-9in placacus and up to 12 6-9in goldfish. it has been a fairly stable tank for about 6 years now.
