The Puffer Forum

Hi I was wondering if some one can tell me how I can help one of my GSP’s. I bought 3 at the store 2 days ago one of the 3 I bought has a black belly which it already had when I got it.

My tank levels are
PH 8
NO2-0
NO3-5ppm
NH3/NH4-0
Tank size is 150 gallons

The GSP with the black belly won’t eat anything even though it’s belly is starting to turn white again. Does anyone have any suggestions.

Any other inhabitants in there? SG? What foods are you offering?

I only have the 3 puffer fish in the tank
I feed them salt water ghost shrimp, live krill, crabs, and some silver sides

Discontinue feeding them fish, they are not piscivores. Have they been treated for IPs? I am concerned about the live krill possible passing parasites to them. Where in the world do you even find live krill? What's the specific gravity?

I managed to get some live krill a year ago and put them in a tank and they started breeding.and as for the silver sides I figured I would try them and the other 2 puffer fish seem to like them. And the puffer fish that is having problems was already like that from the store.

Too bad--never buy a fish that doesn't look 100%. I'd treat for IPs anyway.

You are breeding the krill in a marine tank?

Yes the krill are in a full marine tank with a gravity of 1.025
The gravity in the tank with the puffers is 1.012 as they get older I will increase the salinity until I have full marine conditions.
