The Gymnothorax Polyuranodon is not a true fresh water moray. There is actually no such thing. They are great creatures though. If kept in fresh water after about 12" they will slowly diminish. They need slightly brackish 1.010 to 1.021 to thrive. They are often born in freshwater, but not necessarily, because they live in river estuaries near the ocean salt water. The adults are usually found in pure salt water. wonderful creature especially when kept with two tank mates or more.
You are rather ignorant to say this is not a true freshwater eel like G. tile. Please do not take offense for what I say above.
I come on strong because everybody is so quick to jump and say "oh, it's not really.."You are coming on a bit too strong. Aboslutely no need to talk to your fellow members in that tone ( even when apologizing afterwards )
Apologies are best avoided, not given.
