I need pea puffer help!
We got a pea puffer for our 15 gallon tank with the mollies and platy. She was doing great for a few days, swimming around and attacking snails to our great delight. Then she started spending a lot of time swimming up and down the corners of the tank. Then she started basically floating at the top. I thought maybe she was more sensitive to bad water quality than our livebearers, so I did a 50% change, but she continues to chill at the surface (where there aren't any snails) or to rest on a leaf or our spongy prefilter. Is she doomed?
Water parameters and filtration are fine. This tank has been running for almost a year and we test the water regularly.
15 gal: 1 butt-ton Malaysian trumpet snails.
20 gal: 20+ various molly and platy fry.
55 gal: 40 neon tetras.
75 gal: 2 Taiwan reef cichlids, 3 pelmatochromis nigrofasciatus juveniles.
