hey guys i have had my 12 inch red tail catfish and my 12 inch golden clown knife both pass today... when i pulled the clown knife out of my tank after he was dying (floating up to the surface belly up with his gills barely moving) there was something moving inside of him so i suspect internal parasites to be the silent killer but now im noticing my pbass have there fins rotted on both sides and one of my bass has half of his eye looking cloudy is there anyway i can cure my pbass before they die to or is it to late... PLEASE HELP GUYS I HAVE HAD THIS BASS FOR OVER A YEAR AND A HALF NOW AND DONT WANT TO LOSE ANY MORE FISH.
