A few weeks ago I got Giupetto. He is a red and white HM. He was fine for a couple of days then his fins got all clamped. I treated with maracide and now he looks beautiful. His fins are now healing nicely. However, yesterday he was hiding in his house. He likes to eat at nighttime and wouldn't come up to eat. I moved his house so I could check on him and he did swim up to the top but won't eat. Then I noticed he was sitting with his head facing the gravel with his body up in the air. He was also breathing heavy.
Tank is 2.5 gallons with a tetra whisper filter.
He has a heater which is at 80 degrees.
He has not other tank mates, just some live plants.
I was putting aquarium salt in his tank every other day.
What is wrong with Giupetto?? What do I need to treat him with?
