i’ve had my baby feta for the last 6 months or so and he’s always been very active and curious but the last 2 days he’s been sat at the bottom of the tank and looking bloated, this morning i noticed his scales starting to (i think) pinecone. is there anything i can do? he’s in a 22 litre planted tank with a heater, filter and 2 zebra snails, i’ve also added my parameters the ph is a little high- around 8 but 0 nitrites and ammonia. Please help!!!
