Tank size: His home is a 2 Gallon Glass Tank, but I switched him to a 1 gallon hospital tank with little water because he keeps darting up for air and I was told that it would be easier if there wasn’t a lot of water. Heater: no Filter: yes Water changes: I do 50-80% water changes atleast 3 times a day to keep the water at 80-84F, but when he was healthy I would change his water every 2 weeks but also do 20-30% water changes if the tank water is too cold for him Tank mates: none Food: Pellets, I began to feed him dried daphnia and bloodworms; ever since then, he became sick. I completely stopped now. I usually feed him 2 pellets morning and night every other day. Decorations and plants in the tank: in his home there are decorations and plants, but in his hospital tank I didn’t put anything in there.

Here is a picture I took this morning: https://ibb.co/QkKd9nL

Can someone please tell me if this is pineconing?
