Wondering if anyone can help me...I noticed yesterday that the scales on David Rose's head seem discolored. I checked him again today and it looks like his gills are swollen?? I zoomed in on the photos so you can see it. Can anyone tell me what's going on?? He is eating fine, but seems to be more lazy than usual. He has always been pretty lazy, but yesterday he didnt want to come out at all. I ordered kanaplex and aquarium salt but it wont be here for a few days. I plan on doing a water change today. He gets weekly 25% water changes. His parameters are 0 ammonia, 0 nitrite, slightly higher than 5, but less than 10 nitrate. Ph is steady at 7.4. I had attempted shrimp about 2 weeks ago but they all died, but otherwise nothing has changed. I also got him a new full spectrum light (for my plants) and wonder if he was like this before but I just couldnt see it with his old crappy light. Any advice would be SO APPRECIATED!! I hope my boy is ok!! Also worth noting that my tank is fully cycled and established since feb. It is heated to 78-80° and i have a ton of live plants and hiding/rest spots for him.
