Mothi Posted July 30, 2004 Share Posted July 30, 2004 What fish can I keep in a 20g long that has 22 lbs live rock and 20 lbs of live sand? Do I need special lightings for a marine fish only tank? It has an AC 150, but may upgrade if needed to the AC 200. I prefer fish that can eat frozen or flakes instead of live foods. I like fish that is a little exotic looking, so NO clowns or damsels. I want a lion fish, but they only eat live right? Link to comment
cadesun Posted July 31, 2004 Share Posted July 31, 2004 the only lionfish that will be happy in a 20gal would be a fu manchu in IMO. you can train them to eat frozen foods. Link to comment
Withers Posted July 31, 2004 Share Posted July 31, 2004 there's not much you can keep in a 20 gallon fish wise. even fu manchu lions will eventually outgrow it. you could keep a dwarf angel for a while, a cherub is a good choice, or a flame, or a coral beauty. also, look into gobies and blennies and cardinal fish, they would all be suitable. but i wouldn't try to keep more than 2 fish total, maybe 3 if they're really small, but be prepared to upgrade to a larger tank to accomodate their increasing size. also... if you have 22 lbs of live rock, you do'nt need a hang on the back filter.

Seanano Posted August 1, 2004 Share Posted August 1, 2004 flame angels and coral beautys in my opinion both get too big for a 20gal yes it can be done but theres not enough room. cherub, fireball, flameback angels are fine in anything 20LONG or over. not much of a fish choice? i'd say he has quite a selection, basselets, blennys, gobys, clowns, hawkfish, etc....
