Red Tailed Black Shark?? Tank mates?

If you really want a RTS you need at least 40 gallons! I have one wish I could put him a 50G but he is a baby and will be fine in the 40...

BUT if you upgrade your tank you can put him with any semi-aggressive fish, such as barbs (Tiger Barbs are aggressive, thats what I have mine with)

I suggests joining a fish community forum such as: http://www.aquaticcommunity.com/aquariumforum/inde... they have a lot of good profiles on fish as well as an active forum community. Here is their profile for the RTS: http://www.aquaticcommunity.com/fish/redtailedshar... (though they should get at least 6 inches, and a little more)

Red Tail Black Shark Care

Sorry, but your tank is way too small for a Red-tailed black shark. They need at least 35 gallons. They are even more territorial as they get older. Our gets along just fine with Plecos and neon tetras. But they will feel too closed in if you put him in such a small tank and this will make them even more territorial and aggressive. Please do some research if you don't believe me, such as fish forums, and other people will tell you the same thing.

Your tank is too small for a red tailed black shark.

Well you would think... but you'd be wrong. If you type red tailed black shark care in google it takes about 10 seconds to realize that tank is too small.

I have angelfish with my red tailed shark, and they never bother each other. Of course, i have him in a 20 gallon too, so he has more territory to himself. You can, but i really wouldn't suggest red tails for a 10 gallon :/ Note, that a 10 gallon is only 21 inches in length. Red tails can get up to 6 inches. Also, most 10 gallons suggest that you use them for coldwater fish. But hey, i can't stop you. If you really want one, go for it! I love them! Just make sure you have atleast one hiding place for him. Good luck with your fish!

Like the post mention..... that is too small of a tank for a red tail....you need at least a 50 gallon

Too small. But maybe some neons?
