Last night when I got home I found my blue spotted puffer hanging out under a rock and appeared to have lost color (looked pale white/dead) after watching him for a few min he started to move around the tank like normal and all of his color came back, he also ate like usual. About 5 min ago I set to turn on the tank lights and give them their morning seaweed and the puffer looked like he did last night but this time he was purched at the very top of my LR
formation only moving his eyes. So I came to get my camera so I could ask for advice on the matter and by the time I got back to the tank he was swimming and had his color back. What the heck is going on!?!
