I’ve noticed my albino Senegal with a few bloody finlets the past 2 times I’ve done a water change. I change about 75% of the water every 4ish days. None of the other polys or fish show open wounds. Wondering if the bloody finlets is from aggression (he’s the smallest poly) or potentially from putting PRIME directly in the tank,etc. IDK if his swimming in the area where I poured PRIME would cause burns etc. Any help would be appreciated. He’s acting normal, but want to try to figure out what’s happening. Thank you.
