Yes & that puffer is too fat, I'll admit it. Is that a 5g tank he's in? That puffer needs a 20g long tank & a ton of decor. Puffers are very intelligent creatures that need decor to investigate or they get bored easily & will stress. Your puffer is pacing, which is s sure sign of stress. You need to feed him more than just bloodworms or his teeth will grow too long.

Also, your puffer is a FW fish, so I hope you aren't keeping in in BW.
