Hello all, my betta fish seems to be wedging himself under or in anything he can find. He’s not interested in food, and is not very active. I’ve just put some aquarium salt in his tank for the first time and he seemed to perk up, not sure if it’s coincidental. The medications I have on hand right now are Methylene blue, kanaplex, melafix, and bettafix. Will any of these help? Thanks.
