Hello, I was debating on whether to buy one of these fish or not. I hear they can be picky eaters and that shouldn't be a big problem once finding what they are willing to eat. But also I read that they will eat smaller, top dwelling fish. I don't have any fish that stay at the top of the tank other than my 7 tiger barbs, all of which are full sized. My only worry is my 4 peacock gudgeons, which are newer to the tank and small ( about 1 1/2" ). They normally stay near the bottom or mid level tank but one likes to be near the top corner. Would this fish be food for the AFB? they are longer than most my other fish but very slender. I hope they will be fine together as id like to try this oddball in my 55 gal tank. yes its very sealed at the top and has plenty of floating plants for the AFB ( frogbit ).
