hey everyone! I have a 29 gallon tank, kept at around 84 degrees. I've had 7 tetras and 3 platies for months now, and added 2 corydoras and 5 danios last week. there's only the 1 angelfish at the moment and up until this evening he's been doing great since I got him 6 months ago. he appears to have some splotchy, dark discoloration on his upper half and his fins are all clamped up. I'm very worried about him (and the water parameters are fine).. any ideas what I can do or what could be the problem? thank you!
