I’ve had my Red-tail tinfoil barb for almost 2 years, and it’s about 5 inches. You don’t need to keep them in a 100 gallon tank. Fish are like plants, they only grow as big as the pot (or tank) that their planted in. I keep mine in a 30 gallon tank with 6 other fish. A rainbow shark, 2 orange gourami, 2 tiger barb, and 1 blue green tiger barb. I even bought the red-tail tinfoil barb, rainbow shark, orange gourami, and tiger barb at the same time from pet land (2 years ago) and I’ve had zero trouble. Except for when I tried to add 3 little blue green tiger barb and my shark ate them because the where so little. Well, hope my comment helped with questions they have!

    This is terrible advice, fish don't grow to the size of the tank, it's a myth. What you will do is stunt the growth of the fish but the internal organs will keep growing till eventually the fish dies an early death

    I had tin foils i ended up getting rid of them because they got huge they were in a 55 gallon fish tank they did not stop growing they were getting stressed because they got 2 big & not enough rm 4 them in it

    Just because it has survived your horrible approach to fishkeeping Rylee does not mean it is thriving. Huge difference between it. Your fish are in too small of a tank and by not recognizing this you are actually doing more harm to them than good. And please stop trying to spread misinformation on a very credible site. You Rylee are ridiculous.

I have two red tail tin foil barbs (8in), I just got back from vacation and both sides of both fish are bleeding, it looks like the have been scraping themselves or fighting. Any suggestions on how to heal them?

    Hello Alan, I was searching postings for this exact reason. I just noticed today that one of mine seems to be bleeding too. I have a couple of large rocks in my tank that may have been the culprit. They do love to chase each other and swim around very quickly. They often can be heard bumping into the glass. I suppose all you can do now is observe to make sure he heals okay. I'll probably remove the rocks and just put a few more plants in at the next cleaning. I hope he'll be okay. Good luck to yours too.

    Put 4 to 6 salt cubes (without iodised) into water. Also use general aid drops.

Can I put red-tailed tinfoil barbs with malawi cichlids?

    Your barbs would probably not hold up well unless much larger and a huge school.
  • Tristan - 2012-08-04
    And how long do they take to grow?
  • Jeremy Roche - 2012-08-04
    Depends on feeding and tank size.  Even if the same size these cichlids can be a too aggressive for a barb.

    I have a 5in redtail. Starting to bully my golden severum Chasing around bigtime. Severum is about same size too. Wont touch the oscar yet. Funny cause the Oscar is smaller and severum will bully the Oscar a little but scared of the red tail.

i was searching a place where i could comment or tell story about my fishes. yesterday, my tinfoil barb attached my 5 inch gold fish (size without fin) and taken their both eyes and made them blind, no other injury, i hope tinfoil barb (red tail) is not suitable for goldfish in my views as one of some shopkeepers told me that tinfoil barb is meat eater or it may be dangerous for my goldies.

I have two 10+ year old 12' Red Tail Tinfoil Barbs. I bought a new bigger tank and have been trying to get the PH down to the level of their current tank--6-6.5. Cannot get below 7 in almost 8 weeks. Will they survive the 7 ph if I move them. They have become very special to me and wouldn't want to lose them in the move. In a 37 gallon now, going to 65.

    In case anyone else has this problem, I finally found something to bring down the PH gradually. It is called Acid Buffer. You put 1/4 tsp per 10 gallons of water each day, testing. Brings the PH down about .2 per day. Finally after two months I can move my two fish to their new home!

    I have had red tail tinfoil barbs for 5 years in ph 7. If that's your normal water ph they should be fine.

I'm presently having 2 redtailed tinfoil barbs in a 22gallon tank.They are about 3''.Since the time I've got them,I have been noticing them to always be in the lower regions or rarely in the mid regions of the tank.They never come on top of the tank even when there's food put in.I'm a lil worried about the fish not eating and the water getting polluted.Any suggestions ?Thanks.

I bought tinfoilbarb when it was quite small but in 6 months it has grown almost 4 inches long it was kept along with other fishes like goldfish, silver shark, catfish etc. suddenly it started tearing the eyes of other fishes like lionhead fish, shubunkin, veiltail etc. Why this aggressive behavior suddenly?

    Mine did the same. I have a normal tinfoil barb and the other one is the leuscitic version of it with black eyes and lesser scales. When they became around 7 inches and 1 and a half years old, they killed my juvenile oscar, a big shubunkin goldfish,and angelfishes. You should buy a new tank or sell it. It is most likely a male I guess.
  • Abhy - 2015-05-27
    ya that\s true, the Tinfoil barbs must not be kept with the most peaceful fishes like the goldfish.......poor ones....

I have 4full grown tin foil barbs in a 120 gal tank with 1rope fish, 1eel,1cory cat and a archer. The barbs keep rubbing on the gravel and rock to the point of damaging their selves. They look like they have been descaled. I do a 50% tank change every two weeks . There is no ick and all the other fish are fine, oh and the tank is brackish . Anyone have any idea why they are doing this.

    Sounds like a nice tank with some great fish. If your sure your Tin Foil Barbs don't have Ich, it could be another parasite or some other malady. 'Flashing' (scratching on rocks or gravel) is  usually caused by an irritation of the body, most often the result of  than optimal water quality. It's good that you are doing water changes. After doing 2 or 3 partial water changes over a week, see if they are still rubbing.  Interestingly, I've also read that rubbing on rocks may be an indication of indigestion. Some say it happens with the introduction of frozen fish foods.
  • Bedeanne Marie Ogee - 2014-02-01
    Funny you should say that about frozen foods, I feed frozen krill every 2 days to the eel and rope fish, and the barbs eat the left overs. Wonder if that could be the problem. I'll only put in enough just for the eel and rope fish and remove what they haven't eaten and see if that helps. Thanks for the reply.
  • Clarice Brough - 2014-02-01
    I hope that helps! good luck.

Hi, I have three red-tail tinfoil barbs in a 20 gallon tank. At the moment they are only 3' long and they seem very happy. They share the tank with a Silver dollar the same size and an algae eater. And, how long do you think it will take them to grow up 10'. Do you think I can wait sometime before I have to upgrade to a 100 gallon tank?

    They are slow growers.  It can take years to grow these fish to max size. can get a 55 gallon tank for a midway point upgrade and that will last for some time.
