These are a very awesome little fish. And for the price you can't beat em. Mine is the coolest 2 dollar fish i have ever bought.
Its unbeleiveable what they can fit in there mouths.
I was feeding mine guppies and noticed that it was also eating the flake food meant for the feeders.
So I went ahead and put him in the big tank a year ago. And now it eats flakes,pellets, gold fish, fat head minnows. Or just about anything.
I only wish I could find more of them. I would like to have 50-60 of them in a 150g.
