with a dwarf lionfish

[tang daddy]

hmm 30 reef with a lion fish do you go in your tank much?
I have a 90 and had a dwarf in it for awhile he would only eat small guppies kinda a pain that it wouldn't take frozen, when they're small they have decent colours on it's fin but tend to hide out alot. With that said yours may be able to addapt well to frozen and feed it off a chopstick. I wouldn't be worried putting it with other fish larger than it although once he gets to adult he may try to eat his tankmates.....
