Just wanted to give another update, Pete seems to be 100% back to his old self. I mixed up his diet by adding snails and scuds, treated with aquarium salt and expel, and everyone seems totally happy. Thanks so much for all the advice! I have a 10G tank I think im going to use to start a feed source but I'll make a new thread about that. Cheers!

Thanks for all the advice. I got some scuds and snails for them a few days ago and they love eating them. Pete is still hanging tough, definitely moving slow still but spending less time sitting on the bottom. I think im going to treat the tank with a dewormer, Fritz Expel-P or ParaCleanse I think. Does anyone have experience with these products? Do I need to remove the carbon filter and inline UV light to use this?

I do feed them ramshorn snails as well from time to time but they havent had any in awhile. I'll get some different food today after work today. I know its probably too late for pete but maybe the other puffers will benefit. I got my first 2 puffers from a different shop and they were definitely bigger than the two I got later from Aquarium co-op so its possible they were older than I thought. Is it safe to assume its not a parasitic/fungal/bacterial disease because I havent added anything to the tank other than food? Or should I do some sort of treatment?

Thanks for the reply! I havent added any new fish or plants in at least 9 months, and the ammonia is under 0.25 ppm

I've had this awesome pea puffer for about 3.5 years, and its usually very active and shoots right to the feeding area whenever it sees me and follows me around the tank. However, the last 2 days its been acting very lethargic and resting on the bottom of the tank quite a bit. It seems to be swimming like normal and can rise and sink just fine, and I don't see any signs of skin disease. It doesnt look thin either, just really lazy all of a sudden. Another puffer I purchased with this one died last year after showing the same kind of symptoms initially, but it eventually became very pale. I'm wondering if there's anything I should try to keep this puffer from declining or if that would just make things worse. 2 younger pea puffers in the same tank are doing just fine. Tank Details: 60 gallon sandy bottom and lots of plants No NO2 or NO3 detected pH 6.9, KH~15, GH~30 3 pea puffers, 5 furcata rainbows, 3 kuhli loach, 2 siamese algae eater. Everyone seems to get along just fine. Occasionally the puffers chase each other but I dont see any biting. I feed frozen blood worms once in the morning and once at night. Any comments or suggestions are very welcome! Please help me save Pete!
