I have Biscuit for more than a week. He seemed fine until yesterday he started to be lazy and he seems sick. He just slept all day behind the heater and didn't move. When he inhales there were bubbles coming out of his mouth and gills. He's sometimes swims vertically and just float slowly. He would swim a little bit but then just go into the spongebob house and stay in there without moving. He is in a 1 gal bowl since I'm in college and hasnt got enough money to get him a 5 gals yet. This is his diet
Mon: omega 1 flakes
Tue: bio gold pellets
I also change water every other day and I started out aquarium salt in there along with the conditioning. He ate this morning but after getting back from work. I tried to feed him a bloodworm and he ate it but spit it out.
Can anyone please help ;-( thank you
