Bloated Angelfish

I have a suddenly bloated Angelfish that can not longer swims, just sits on the bottom of the tank. I would like to treat it with antibiotics but am not sure whether I should treat the whole 55 gal tank or seperate and treat singley. Please help as I am getting new fish in tomorrow!

You can treat him on the tank but the best way is put him on a separate tank.., aclimate him well, remove media and people use 1/8 of a teaspoon epson salt per 5gl of water..(the reason why put him on a separate tank is because some fish dont do well with salt.., im sure theres other treatments but i tried this once and it worked..., and good luck with the fish sometimes it may be too late...

And also feed less until is completely cured..

Bloat is usually caused from over feeding. Try putting him in another tank and fast him for about 4-5 days. Then feed him only crushed frozen peas removed from the shell and warmed for two to three days.

The clown loaches finished him/her off :(

Aww that's to bad. Sorry.

Bummer mate... bad luck..
