My betta Ziggy had a red thing coming out of his face below his mouth, Monday the 24th the local fish store removed it, told me he was very healthy, and water test came out great. They gave me BettaRevive to help with healing. He lives in a 1 1/2 gal tank. Tue pm he developed a cloudy eye, on same side where red thing was removed and would not eat, stayed at bottom of tank. Fish store said not to worry, it was Cloudy Eye which BettaRevive would heal & to continue treatment. Today he has that red thing again. He's still not eating and he's very lethargic. Any ideas?
