I agree with whoever said Scarlet Badis.
Heavily planted with dwarf puffers! :thumbsup:
Yeah, except that those are not the easiest fish to keep. You will need to culture your own live fish food, like grindal worms. I wouldn't try anything smaller, as I find it to be wasteful since the fish don't eat most of the tiny worms.
That's part of what makes them interesting. Challenging fish can be very rewarding.
