Yeah, the livebearers will breed like crazy and I don't see any other fish in there that would actively prey on the babies. I used to keep platies with angels in order to keep the population in check.
yes they will eat plants! LOL...Oh, almost forgot. I've been told that dwarf cichlids will eat plants. True or no? Cuz that would be bad, very very bad. Would love to have some though, pretty little fish.
You might want to consider purchasing a 10 to 15 gallon and raising some of the livebearer fry. I raised White Cloud Minnow fry (started with 4 adults, now have about 15 White CLouds) and it really is interesting and a lot of fun.I don't really want to fish out babies to feed to the pond fish, poor little guys. More likely to just let nature take it's course within the tank. Who knows, a few might live. (But not likely)
Five votes for more fish......looks like my hubby is gonna loose this one! lol Sorry hon!
