From the moment Gershwin arrived, he has bitten his tail. I have been struggle to keep from being stressed out and bored. His tail developed a little fin rot which I started treating with medicine and frequent water changes then moved to salt. The last couple of weeks, I saw a big change in his behavior and regrowth in his tail. About the same time I started adding salt, I changed water conditioners to what came with my tank.
This past water change I ran out of the water conditioner and ended up using his old one. Now his tail is shredded from his biting it. Could it be possible he doesn't like this water conditioner? And can you put too much in there? Sorry if this is a dumb question or has been asked before. I looked for it but couldn't find it.
