Questions & Answers
I thought my Betta had fin rot, but there was only discoloration and a fraying of the ends. I put him in a new, clean tank treated with aquarium salt with daily water changes. Seemed to help but no new growth. Today his gills are slightly discolored. He is eating normally and active, but no bubble nests. He's in a 2.5-gallon tank, unfiltered with live plants. I've been doing 100% changes twice a week. All his water parameters are in safe ranges?
Can you help me? My fish has been sick for about a month. I've tried everything. He will have fuzz on his back that looks like Columnaris. It'll go away a little before it returns looking like a dandelion! I feel terrible that I can't help him...the fuzz looks like that in the Columnaris picture, but it could also be fungus. I've treated him with Lamenting and Metronidazole, and then fungus cure separately. I have also tried Methylene blue. Please tell me what I can do.
My betta has had a gill puffed out a bit for about two weeks now. I started to use antibacterial drops to help him out, but he's been hiding in his castle, and hasn't eaten in a few days. I recently changed his water and noticed that he had red things on the ends of his tail and fins. What could this be?
