spamming my way to the top...
from what I understand the puffers might be bored lol. your tank is pretty large and I think if you just chuck in loads of decor/plants they will be fine.
nice flounders

ok thanks, i put more snails in for them and they love them
is it just me, or do those puffers look like T. fluvitalis more than they look like T. biocellotus?
I'm pretty sure those are figure-8 puffers. It's not so much the pattern, but the presence of a pair of eyespots on each side of the fish, one close to the base of the dorsal fin, and another on the caudal peduncle (the "tail"). While T. fluviatilis can have quite complex yellow-green squiggles on the body, as far as I know it never has those eyespots.
