Hi all, I have a blue spot puffer that I purchased a couple days ago and it seems to be ok but I'm not sure, this morning I came down to the aquarium and he is kinda swimming different. Sometimes bumping up against the glass and kinda just letting the water take him wherever. Seems to have control over where he goes though, maybe just choosing to go with the flow? Is he ok? Apparently I cant upload video of him. I just noticed there is something on its skin maybe? Also his eyes look maybe a bit glazed but I dunno. What should I do, I dont think he can swim very well, he keeps getting in the corner by the heater. I quarantined him in a box and now he at least isn't bouncing around everywhere but he also didn't eat the food I put in.
