Unfortunately you are wrong,
the groupers are part of the family Serranidae, almost all are salt water but a few are brackish, some spend part of their time in freshwater, and one is a freshwater to brackish water fish and (as far as I know) has never been found in full seawater. It is the white-dotted grouper (Epinephalus polystigma), it is an attractive fish that I have never seen sold, pity, becuase it would be perfect, getting to a max of just under 16" and breeding in brackish and freshwater as small as 8" long. here is a picture by Randall.
The Bumblebee grouper is a huge and rather unattractive fish as an adult and has been recorded at around 10' long and 800 lbs. Keeping them in freshwater lowers there resistance to disease and I have found no records of them reaching any where near maturity in FW, they seem to requie more and more salt as they age and by the time they are 4-5' long (in the wild) they are solitary hunters near reef systems. IMO they are not a good choice for private fish keepers.
damn it, to far for me to go fishing for one! ahwell. maybe if enough interest is shown, maybe someone will get one inIndonesia, the Philippines, Papua New Guinea, and the Solomon and New Ireland Islands.
good oneI know they are just fish, and you can always eat it, but keeping them when they are small, knowing that they will die young, strikes me a bit like drowning kittens when they are no longer cute.
I mean that I have never heard of one in a private tank that survive more than a couple years or got bigger than 2'. I also mean that I think that out of the few I have heard of people aquiring over the last year they are also now dead. There maybe exceptions but not many.is their any way we can change it not to grow bigger than 10 inches to keep it nice and fun. "guppy" do you mean it will have a shorter lifespan if changed to fresh water? i like colorful fishes and some predatorial fishes are just not too colorful for me. not to derail this but yellow on fish is really nice or super red arowana (nah.. illegal.. i'll keep my distance).
