So, I have a heavily scaped 450 with a 150 gallon sump. One of my plecos has been unable to put on weight for the last month. She is six years old and ten inches long. She still eats well and has normal looking feces. She is just skinny and constantly forages. I feed the tank zucchini twice a week in addition to the normal feedings. I suspect internal parasites. The only symptoms are the low weight. I have prazipro on hand and did the Epsom salt soaked food for a solid week to no effect. Suggestions?
