I have a 20 gal established tank. I would like to add fish to it and I would like suggestions. I used to have a ciclid, but I traded it in cause it got too big for the tank. I would love to get some more ciclid but I'm not sure what type can live in that size tank. Could you help? -Thanks, Casey
 
Most calvus will live in 10g if alone, so a 20g with a few community fish should work :)
 
I used to have 6 black ruby barbs (puntius negrofaciatus?) in my 20 gall high. They don't get very large and they are not extremely aggressive. They also eat algae.
good luck
:)
 
If the tank has been fishless for very long (more than 3-5 days) and you have no source for ammonia, the tank is no longer biological 'established', and you will experience ammonia spikes when fish are re-introduced.

There are many dwarf cichlids that would be happy in that size tank, depending on other parameters. Apistos would top my list.
 
Use the search feature to find a thread in the Cichlids forum entitled "Shellie Links". That will tell you about a beautiful Tanganyikan dwarf cichlid suitable for a hard alkaline tank.
