Long time no see guys!
My big boy has recently started showing some swim bladder issues and I'm wondering if you guys can help.
60 gallon "cube" tank (2ftx2ftx2ft), planted with onion plant, anubias and various crypts.
Set up and running for I'd say 3 years? Something like that, with these fish as the original occupants.
Inhabitants were originally 3 ryunkins, 6 WCMM's a bristlenose pleco and 3 dojo loaches, over the years that has been reduced to two ryunkins, one dojo, the bristlenose and one remaining WCMM.
The ryunkins are.. oh, I'd say body size is about that of a pool/billards ball?
Water change schedule, 50-80% on a weekly basis. Nitrates rarely go over 10.
Feeding schedule, normal food is New Life Spectrum Goldfish Pellets SOAKED until they are soft daily, once weekly they get blanched zuchanni slices and about twice weekly they get a thawed out "fruit cube" of diced up apples, oranges, garlic and zuchanni that I blanched, then froze in an ice cube tray. Usually I will give them a fast day.
The problem.. ever since I moved last July, my male has been showing what I think are some swim bladder problems. When resting, he is always verticle, nose up, tail down. He'll stay like that for hours, that's the way he sleeps at night. He does not have issues with floating, in fact, he will drift down if he doesn't correct for it.
As far as I can tell, I'm doing everything correctly. I did lose my one Ryunkin early on due to swim bladder and tumors, but she was always stuck upside down and floating, very different from this.
Any ideas what I could do to improve his quality of life? I do think the water has something to do with it, none of my tanks have looked that great since I moved (my one puffer lets me know asap with skin problems, massive water changes help but I have to do them more often than I did before moving). I use RO water with the more sensitive fish, but there's no way I can manage to do 50% weekly water changes on this goldie tank with RO water, plus have enough left over for my sensitive fish (the filter takes forever and I have to store the water until I have enough to do changes).
The only other thing from the water that's changed since I moved is that now that I'm on city water, I use Prime as a dechlor. I've never used it before and I doubt that's causing any problems, but thought I'd throw it out there. I've always either been on well water or used Yamato Green's NoChlor.
Thanks in advance for any suggestions.. He seems healthy otherwise but it just bothers me to see him rarely swimming "normally".
