Ok. I've established a few things with these fish. They love live blacks worms, frozen bloodworms are ok, live bbs are great, and little bitty crayfish are attacked by the wolf pack the eaten.
Pufferpunk. Females are more rounded right? If not, how do I tell the difference? If they are more rounded I have one male and the rest are females. But there's one that doesn't hang with the pack all the time. Could it be there's a dominate male already in the pack? I've not noticed any disputes between any of them. The one just does it's own thing and hangs with the pack when it decides. Or to feed.
Also... There are some really small snails in my greenhouse koi pond. Like the size of a pin head. Can I feed them to the puffers? Or maybe put a few in the tank and let them grab them on thier own? There are also a bigger snails. The biggest the size of a dime. I didn't add them so they either came from the plants or some other unknown means.
And last but not least. The ponds, lakes, streams, and rivers are full of freshwater shrimp. I laugh when I see them in pet stores now. A net and a bucket and you can have tons of them. Anyway... I know the puffers are only going to get an inch or so. Think they could manage to feed on a small freshwater shrimp? Around the thier same size.
I'd like to offer them a varied diet. Black worms seem to be a must. And the crayfish. If the snails and shrimp will work I'll keep it to those 4. I'm not interested in raising bbs, and like with the frozen bloods worms they just nibble them. They'll have one, and ignore the rest. The cories love them however. Also the flounder.
I saw a 45 gallon breeder tank at the lfs when I was getting another cory and think I'd like to get it for 15-20 of these guys. I liked the fact that it was wider instead of taller. Say like a 55. I'm a big fan of larger fish, but these guys have me in front of thier tank more than the others. My oscar is intelligent. But these puffers are in a class of thier own.
