My beta fish has developed a blister looking bump on his face recently and it’s gotten bigger and bigger does anyone happen to recognize it? I can take more photos if needed it’s just hard to get a picture of him because he’s usually sitting on top of the heater or in his castle. I’ve given him pimafix for a week and now we’re doing metafix (3rd day) at a lower dose because I saw it’s too strong to give full dose to beta fish. These were recommended by our local pet store. But I’m starting to get a little worried that there not working Thank you for looking I really appreciate it I would hate to lose him..
