sooo my room in the basement kept getting hotter and hotter, and I checked the temp of the tank to find the temps had climbed to 80-82 degrees F. I added zip loc bags with some water and ice, and floated them one at a time in a quiet corner, and over the course of 2 or 3 days got the temp down to 75-76. Now I use an AC to keep the room cool, and the temp is stable.
at any rate, as soon as i got the temperature down one of the tetras started hanging out at the top of the tank. he wouldnt gasp at the surface, he just stayed a few inches below the top of the water, and he stopped eating. His colors completely faded and his belly turned opaque and white. less than a week later I noticed one was missing, and the other day vaccuming I found him hidden behind some decorations dead :(
monday I see another one start to get pale, his colors eventually faded, and weds night I found him stuck to the filter intake, his belly was opaque and white too :(
ANYWAY the tank is a 29 gal, holding steady at 75 degrees, and every other fish in the tank is lively and happy as they were 2 weeks ago. the remaining inhabitants are 14 (now 12) glowlight tetras, 2 bala sharks, 2 cory cats and 1 pleco.
I dont have params yet but I'm going out to petco (shudder) in about 10 minutes to buy a test kit. any ideas?
