Cleanup crew possible in a 3 gallon with a puffer?
Picked up a 3 gallon (roughly) for my Mom on her birthday as she was enamored by my dwarf puffers. Nice little cube has a little HOB and pretty well planted to boot. Grabbed the Finnex Fugeray Planted+ as she wanted to grow "pretty plants" and quickly found out that was overkill... lol
The easiest solution would be snails for the glass, but I can't do those due to the puffer. Is there a type of glass cleaning snail they will leave alone by chance?
I have a half-dozen now in various tanks, and they have actually never eaten or picked on another fish oddly enough, but that tank is too small for another fish. I had considered a few shrimp as they don't eat those either, but ghosts are all I can easily get and they die in a week or less naturally. They also tend to steal the food from the puffers and carry it off.
The other alternative would be to swap out lights, I'm not sure what would work and not be overkill for a small tank like that.
