Daisy has what looks like possible tears on his tail fin. I can’t tell because of my very poor vision and the fish is almost constantly moving or in a spot I can’t see him at. It’s very possible that it’s just his tail fin growing because it looks like it only on the outer rim of the fin. Also happy to say daisy is getting a new color, he is getting a dark blue trim around his pelvic, anal and now tail fin and hoping it spreads to his dorsal. But what do you guys think. Also the water quality is perfect but the water I’ve just realized it oddly cold. I don’t actually have a heater in my tank. It was lost while setting up and don’t have an extra. But estimated temp is maybe 73° The heater is set at 79° but for some reason hasn’t been working. Brand is marine land.
