Hey

How long would it take for a bala shark to grow full size in a 55 gallon tank

And will it grow with other fish in tank

in my tank i have One Bala Shark,One Rainbow Shark,4 Clown Loaches

How big is it and the Rainbow now. I think I read some-where ( I could well be mis-informed) that when the rainbow gets bigger it may be too aggressive for the Bala. I'm sure there is some-one on here who can advise better.
