    Hi, I came across a fish, which is similar to red-tailed black shark but has a mouth of a SAE at NA. Anyone knows what's the name of this fish? Very interested to get this fish but would not get until I know more about the fish. Thanks.
    Cheers,

    I'm far away from NA to see for myself. Could it be red-finned shark (aka rainbow shark)? I have two of that fish and they do eat a lot of algae, filling up their belly with that stuff. Mine just wont come out during feeding time, surviving mostly from algae (and perhaps small bits of food scraps).
    Too bad they are quite shy and can be hideus, working inbetween shadow, resting in the cover of holes/caves.

    That is just my best guess, never seen red tailed SAE before

    Here is a juvenille of rainbow shark



    and it grows big like this

    it could also be a garra, a picture would have helped to tell you what the fish was.

    Thanks for trying to help, guys .

    It looks almost the same as the picture posted by medicineman except that it has only red tail. All other fins are black with white edge. The mouth is pointing downwards (like SAE). Very beautiful. It's really love at first sight.
    Cheers,

    If you are refering to the fish at the back of the shop where the plants is, it is the fish Medicine man pointed out.
    Something about the water & the fishes that calms me down.

    That's right, Michael. They put a few in their planted tank. However, I'm sure those fishes only have the tail red. I'll do some reading on this fish before getting 1. Thanks to everyone for your efforts in helping me to identify the fish.

    Epalzeorhynchos bicolor. Red Tailed black shark. One beautiful fish, but it is quarrelsome amongst its own kind.

    They are not little to start with and will reach 15cm in size. Haven't read any reports of unsuitability for planted tanks, but as they are quarrelsome, they would do better in a large size tanks.

    There are actually 2 similar looking fish, Epalzeorhynchos frenatum (there is an albino form) which has red in all fins and E. bicolor which has red in the caudal fin only.

    From most literatures that I found, E. frenatum is the one which is mainly associated with algae eating.

    It is not mentioned that E. bicolor will eat algae although it does not mind vegetable matters in its diet. I guess it may still eat algae, probably not as efficient.

    So for algae eating, E. frenatum sounds like a better bet than E. bicolor. Be mindful of their aggression though.

    My 2 cents.

    What you see at the pic that I posted (from my own collection of fish) is E. frenatum, in normal form (there is also albino form, creamy white body with similar red fins - not just the caudal). The do eat algae, to less extent if compared to SAE. Their appetite for plants and moss is very small or almost none, hence much less destructive than SAE but yet also less effective algae control. They are territorial, but not highly agressive, so far I kept some in large tank, harrasing only its own kind. They are hideus shy creature and rest unseen. I have not tried E. bicolor yet but we do have that fish once in a while in the local market. Mine grows from baby to almost full size within months, thanks to abundance of food and space to grow.

    Do you guys think they are agressive towards the cigar fishes? I know they are agressive to similarly shaped fishes...
