I need help, I've been trying to figure out what's wrong with my poor Ryukin Bert, he was fine Thursday night, Friday morning he was not himself, he's always very active always greets me when I walk anywhere near the tank and he didn't swim up didn't acknowledge, was moving slow, looked spaced out, and was floating aimlessly. He's just declined everyday since. Currently I have moved both fish over to qt, I tore down my tank, bleached everything, I have no idea what's wrong with him. Physically he looks fine. Idk if it's from the hose I do water changes with I've never ran bleach thru it since I've had it about 6-8 months now. I bleached it today and I will bleach often after use. Any ideas on what could be wrong or how to treat? I have metro, I ordered kanaplex just in case. I don't want to lose my baby. I just don't know how to help him. Thank you in advance.
