I have Calico Fantail with what is now a long standing swim bladder issue (5 weeks). I will be posting my water parameters and methods already tried to resolve in due course.
I've posted a video to demonstrate some of his swimming, but to be fair, he makes more of an effort when he knows I'm there. If I see him from across the room, often he's just floating upside down on the surface.

~What type of fish is afflicted? Calico Fantail, approx. 8 months in tank. Shares 55 gallon home with one healthy (and cheeky) Black Moor, and one Black Ranchu.
2~What are your tank parameters Ammonia 0ppm, Nitrites 0ppm, Nitrates 20ppm, temp 68-69 degrees Fahrenheit
3~ How large is the tank? 55 gallons, set up 8 months
4~What type of filtration are you using?Fluval U4
5~How many fish are in the tank? see above, small Black Ranchu, 1 inch, larger Black Moor 3 inches
6~When is the last time you did a water change and vacuum the gravel? 40-50% water change weekly, gravel vaccuumed weekly. Without fail
8~Have you added anything new to the tank--Nothing new added, use Seachem Prime to condition water
9~What kind of food have you been feeding your fish, have you changed their diet recently? Feed sinking Tetra pellets on a daily basis, feed peas to aid bowel movement, they love spinach, bloodworms and daphnia occasionally.
I've tried increasing the vegetation they eat, I've tried fasting as suggested elsewhere too. I've tried sitting it out to see if any improvement, but seems worse if anything. Hate to see the little fella suffer (if this is the case). He still feeds fairly normally , although this seems to be harder for him as his buoyancy varies.
I have very reluctantly read up on euthanasia, I don't want to go down this road if I can avoid it, but something needs to give.
I appreciate any advice, and thanks.
