Hey, I have long fin white cloud minnows. Last afternoon one didn’t want to eat but stayed in a corner. I panicked, it was in the same spot my hill stream loach choose as he died. (Water got warmer suddenly, I have a room temp tank) I didn’t know what was wrong but I ran out of the room to get something and when I got back a moment later he was swimming along like nothing had happened.
Last night I found him there again. Not moving, “resting” upright on the substrate in the corner of tank underneath my filter. After googling I did a 50% water change and soon after that he started swimming with the rest of his minnows.
This morning he has gone back to the corner. However I just caught him swimming around again?? I am so confused and not sure why he is acting this way. He is swimming a little slow and disinterested… his fins are droopy, like he’s tired.
Tank Info: started in Dec, 16 Gal, room temp, scheduled light, planted, shrimp, snails, minnows
Water: temp 64-68, PH always steady but low ~6.5, KH ~40, nitrate and nitrite at 0. No ammonia.
Recent change: hill-stream loach died due to sudden warmer water, air stone-like attachment added- attempt to save loach (I took off this morning maybe affecting minnows negatively?)
Possible problem?: 5 1/2 month submerged spider wood has orange spots slowly covering the wood, mostly on topside of wood (none growing underneath), wood breaking down? This has been going on for a couple weeks now. (See pic)
That’s all I have, if anyone knows what’s going on please let me know!
