Jc1119;4762091; said:The poop issue has me thinking it's something else altogether. New fittings should be fine. I'd continue with the wc's and try to get medicated food. Most infections are best treated from the inside out and unless you know for sure what the issue is, dumping meds into the water can overstess already stressed fish and you might not be be treating the right thing. Wc, food and monitor would be what I would do. Good luck!
Thanks again. I will try the medicated food if they will eat. I usually quit feeding them if I suspect water problems to prevent further polluting of the water. Never used medicated foods. Any suggestions?
