MY Bettas fins were growing back after an issue with fake plants. Now he has more rips than before. Should I try aquarium salt or go right for a methaline blue bath? I do have a snail and that's why I'm hesitant. He has no fake stuff in his tank besides the heater, filter, and thermometer. My new betta keeps hiding behind the filter. (I was smart by putting a bag around the intake) he also isn't eating. I tried pellets and worms. Could he be stressed? Is there anything I can do for him to help him through the transition?
