Hi all, I’ve not kept fish for very long so I’m still quite new to this. I saw one of my geos acting strange today, I think it’s the male as it’s the largest and most coloured up. Is this breeding behaviour?
Also I’ve noticed that his fins on the bottom have gone black! Any reason for this? I’m sure they weren’t like that yesterday! All the others’ fins are fine and my water parameters are ok (0 ammonia, 0 nitrite and 5ppm nitrate).
