Rainbow Sharks

[Cavafish]

I have just been given 4 rainbow sharks to rehome and I am really not sure if I should keep them. I have a 400litre community tank with alsorts in it and it is getting quite crowded. Are 4 ok to keep together? The people who gave them to us said that they have always been fine together and that was in a 240-300litre tank. (not sure of exact size)

Will they get more stroppy as they get older? How big will they get? I have 4 silver (bala) sharks 2 quite big, 2 still small - will they terrorise these fish?

Please help. We would like to keep them as they add a much needed splash of colour to our tank but if they are going to be a pain then they will have to go.

Would keeping one be better/ok?

Any help gratefully received!!

Cheers

I don't believe they like being with others of their own kind..

It would be best if you could just keep 1..

in a large tank, such as yours, provided there are plently of hidey holes
I can see the 4 doing ok. they will set up their own territories;
however the occasional spat will happen and this may result in some fin shreading.

the descision you need to make is
can I bear to see that happen or not.

if not then rehome 3 of them.

in my 400ltr I have a RTBS and a Ruby shark and they stay at each end of the tank

rainbow sharks are quite territorial. so expect some damaged fins. they grow to be around 8" long, though i havent seen them much bigger than 6". i dont think your bala sharks will be affected. i think its a matter of judgement. give it a try. if theres a lot of chasing during feeding time, give a few away.
