Came home last night and noticed this red sailfin cory looking bloated and swimming weird. This morning I could tell it was still bloated, but was cruising along the bottom with friends so I couldn’t tell about the swimming. The others all look ok. I’ve had them for about two weeks, only thing else in the tank is some Cherry shrimp. Any clues as to what it could be?
it’s a 29 gallon planted aquarium. Ammonia and nitrite-0, nitrate-20ish, ph-7.6, hard water.
