Hi, um I'm not sure where to turn for this and I've been a follower for a while, but I trust your judgement and knowledge. I bought a beautiful grumpy betta boy on Friday and had left my tank to run and cycle for two weeks beforehand. Today I noticed that he had a fungus growing on his caudal fin. I lost my previous betta boy to a fast growing fungus and I don't want to lose this one. What should I do?
oh noo!! okay, jsyk he was probably already carrying the fungus from the petstore, almost all bettas are due to the poor conditions they’re kept in, this is not bc of your tank
my advice is to first identify what kind of fungus it is the best you can, sometimes finrot looks like a fungus, sometimes its a piece of tank debris caught on his butt, either way 100% of the time it’s best to know what you’re dealing with BEFORE attempting any sort of medication as this could worsen the problem (or make him immune to the meds when he actually needs them)
Here is a handy graphic on the Betta First Aid Kit (note: it’s generally a better idea to get actual medications from this list rather than “”betta fix”” as that’s just miscellaneous oils and chemicals marketed as a “cure-all”)
i hope he gets well soon, and if u need to u can definitely drop me a line any time for more help!!
