Well, I don't know what to do. If you've seen my other threads, I had a 29 gallon BioCube get hit with Brooks. I got four survivors into the HT. They all got Formalin bath treatments. One didn't make it after the last bath. My DT started its 76 day fallow period. About 1/2 thru the fallow period I had an unexpected ammonia spike and the Melenarus Wrasse got ammonia burn. Got that treated and he seemed good except he seemed blind. Then about a week before fallow period ended, the Coral Beauty got a bacterial infection. Hit it with meds and it seemed to clear up the infection - but left the CB blind as well. The 3rd fish - Pajama Cardinal fish is fine and back in DT now. I've tried everything I can to feed the sick ones. Their favorites. Garlic. Selcon. Nori banded to PVC and in a clip. They just swim into the food, bump into it and swim on. They are wasting away. It's been over three weeks since I've SEEN either one eat. The back 1/3 of the CB is almost paper thin. The Wrasse is struggling to keep from turning belly up. I'm torn between watching them slowly die or euthanizing them. It's gotta be suffering starving to death. Is the a humane way to end this? Or should I just let nature take its course? Advice is welcome.
