Hi, I have a 55 gal tank with 4 African Clawed Frogs, 2 Spotted Pimelodus, 2 Sailfin Plecos, and a bunch of Goldfish num nums for the frogs. The Frogs seem to be having a problem catching the Goldfish. I usually buy 4 dozen at a time, and when I first put the Goldfish in the tank the Frogs can eat them. Now they almost seem uninterested in the Goldfish. I had been hand feeding the Frogs Nightcrawlers since they were babies. Over the past 3-4 months I've been trying to switch them to Goldfish, but I have about 10-15 that have been in there for a month now. I'm sure the frogs are eating, bc they probably would have died by now if they weren't. Anyone know if there is anything I can do, or know if there is an alternate food I can feed them instead?
