ive been doing some reading. in preperation for hopefully a new tank soon.

i used to have 125g tank with 2 oscars in it. a long time ago.
and im itching for another tank where i can enjoy them eating live food but have much more limited space now.

so i was looking into convicts. seems they will eat anything that can fit into their mouth but are also much smaller.

im guessing guppies, snails and shrimp can be eaten?

also if i want to get say 2, should i be aiming for both males or both females or does it have to be a pair. i rather not have babies to be honest, but i suppose if it has to be a pair for them to get alot then i can make do and give them to the LFS. i havent read anything in particular about them being aggresive to each other outside of when a pair is protecting their eggs, so i figured i'd ask.

thanks.
