My male BD been acting weird this week. Hanging on his side behind a piece of wood. Thought he maybe knackered from chasing the females around for the last few weeks. But I just noticed his eye today. It is red over the pupil. Eye is intact but the front of it is all red. Hard to get a shot of it at the moment. Going to up temp and make sure water good. Hope to god he is okay. Around 16" disc.
