OK i have a tropical fish tank, the guppies and mollies wont stop having babies what fish will eat the babies?

Question

the tank is 60 gallons and i was thinking of getting a crayfish. the tank is getting over run by all these guppies and i need a way to get rid of them, i dont want to just kill them, but get a fish or other animal to eat ONLY the babies, or at least not wipe out the fish population... any suggestions on how to get everything under control?

Answer 1

Tiger barbs.

Answer 2

Angelfish will eat all your babies, but they might also bite on the tails of the adult guppies. Be careful

Answer 3

Angelfish.  You could place 4-6 angelfish in the tank, and they should leave the adult fish alone.  And they're fascinating to watch.   Get medium sized ones though.

Answer 4

I have a Kribensis cichlid in my tank for exactly that reason. A single fish wont attack adult guppies ( a breeding pair might), but it does a good job hunting down stray fry.

Small loaches like zebras or yoyos are another option as they are also bottom hunters, which is where the guppy fry seem to hide.

I wouldn't use angelfish, they grow a bit big and start looking at adult guppies as a meal as well.
