My Purcupine Puffer hasn't been eating for over 1.5 weeks now. I've lost my Yellow tang 4 weeks as she decided to stop eating as well. I've had this tank set up for over 3 years now. My water parameters are the following:
Nitrates= 10 ppm
(been constant for 3 years)
Specific Gravity: 1.023
Temp: 81 degrees
I feed him frozen krill from my hand every other day, the opposite days I feed him marine formula mixed with squid. He has been the biggest and best eater out of my tank for a very long time. He's approx 3 inches long and he's living ina 50G tank. His other tank mate is now only a ****sel.
The only difference in my puffy's looks are that he is getting skinnier and that he has a few darker spots on him ( I've read that this is a sign of stress)
Any help is appreciated.
