The Puffer Forum

I have had two pea puffers for 5 days and one of them is really not doing well. She seems dull and thin (almost sunken in) and mostly just hangs out in the corner by the glass or, once or twice, lays on the substrate. I saw her eat two days ago but she wasn't interested last night and has been getting less and less active. A few times I habe thought she looked like she is breathing hard. By contrast, the other puffer is very active, constantly exploring and poking around, is very vibrant and has a nice round belly. I have been leaving the lights mostly off while they settle in, and, while I am hoping to add more plants, there are a few smaĺl plants and rock and driftwood for hiding. Please help! I read a lot about these guys before bringing them home and it kills me that I might be missing something because I am somewhat new to the hobby.

My tank:
They are in a 15 gallon tank by themselves, save one or two ramshorn snails they havent eaten (I was going to add another pair in a few weeks) When I tested the water two days ago it was: PH 7.5, Ammonia 0, Nitrites 0, Nitrates 0.2. I did a 50% water change Monday morning after noticing that the one seemed a little dull and listless, and another 20% change last night. I cycled the tank for a little over a month. They are in a fluval flex, and, since there is a lot of extra space in the filter area, i added some extra bio media from my other tank.

I am worried that, because I am not super experienced I have either completely missed something or don't know what to look for, any advice would be much appreciated!!!

Was he skinny when you purchased him? Most likely internal parasites but he has to eat medicated food. So if he's not eating, it may be too late for him. What food are you offering him?

PPs right, other than that- it’s Pipette force feeding meds. And to be very honest, unless the DP is full grown, and even then... it’s a gamble and is hard with mouths and feedings that small. Not impossible, just hard work.

Thanks for the replies!! I have been feeding frozen bloodworms and I have offered a few tiny snails which they were interested in, but didnt eat. Should I seperate the other puffer?

IPs are passes from 1 fish to their tank mates, through feces, so even the "healthy" ones need treatment.

Thanks!!! Very helpful articles. I also offered them brine shrimp last night and they both ate very well, so maybe I will be able to treat them. I have ordered a bunch of plants that should arrive soon to help make a homier tank for them.
