Just put him in his new home last night (3 1/2 hour drip, from 1.019 to 1.025 salinity). Sounds like this guys has had some rough times lately. Got him from a friend who saved this guy and 3 brothers or sisters, from a 400g that leaked. When my friend arrived, they were found in 1" of water. Only 4 out of 6 sailfins survived the flood, no other fish did. I hope he enjoys his new home for now.
