Freshwater Flounder

[acidburn470]

I was thinking about getting a freshwater flounder and was wondering if anyone has one, and if they could tell me what they think about it.

theirs a freshwater flounder?

There are several that will live in freshwater when young, most do better with brackish but some like the Achiropsis natterei are true freshwater fish, that one is from the amazon. They all tend to be fin nippers and like live food. To say more I would need the species.

Achirus lineatus this is the name of the one I saw at the fish store.

The lined sole is a brackish fish that will live in fresh water while young but tends to die younger and smaller without salt (at least 1 teaspoon per gallon). It will eat flake or granules while small but prefers small inverts and baby fish. It seldom lives long enough in fresh water to reach it's full size of around 7". It comes from the southern coastal waters of the US and tolerates tropical temps quite well. As an adult it will eat guppy to small molly sized fish and small shrimp as well as worms. It is very similar except in temp. requirements to the dabs I used to keep from the river in Wa state. It would do well in a molly tank with some pipefish until it got big enough to eat them and shiner perch as an adult. You could keep one for life in a 29g easily. They sometimes nip fins but are peaceful enough with its own kind and fish to big to eat. This information is a mix of my own exp. and several fact sites.
Oh, they grow slowlyso it would take acouple years to go from 2"to adult.

I have a fresh water flounder, he's pretty cool I love that guy, he hasnt nipped at my fish he leaves them alone, my fish dont pick on him, he stays content he's neat to watch sometimes also. He doesnt need live food he eats off the flakes, freezdried worms and pellets that sinks to the bottom, hes about 2 1/2 inches so I guess I'll watch for this eats live food thing, so far so good without it.

Is there a flounder species that is purely freshwater or do they all go to brackish as they age?

Guppy answered your question, please pay attention.

[acidburn470]

Guppy only discussed one species of Freshwater Flounder that is why I asked are there ones that are only freshwater. Cause he described the Brackish species

Look for a hogchoker, or more info on 'em. They are native to the springs around here in N Fla, and from everything I've read they are fresh all their life.

[guppy]

Hogchokers are fish that give classifiers fits, they will happily live in everything from full salt to totally fresh, I have read that even the freshwater ones will move to somewhat brackish to breed but if you are not breeding it then who cares? They get about 8" long. They do prefer temps a bit lower than most tropicals and the wild cught ones tend to have flukes, they show uo as dark spots near the base of the fines if you backlight them. Just use a antiparasite medicated food like the one made by jungle during your 10-14 day quarantine, They will eat small fish.
There are more flounders and soles that will live but not breed in fresh water. you just need to ID your fish to check it out.
Even some of the tongue soles will live in fw (most of the Cynoglossus sp.) and some will breed there like the two from Borneo/Sumatra, the C. kapuansis (11") and the C. waandersii (4"). I have never seen them for sale but they are not rare fish.
The C. arel and C. bilineatus do show up in stores sometimes and they get a bit more than 16" but can't be bred except in salt water.

Great Thread!

Also curious on the specifics for this species: Achirus lineatus.. That is the lined sole that you described, the brackish one?

I am interesting in importing these guys, however I am unsure of how well they would sell via internet..

I wasn't able to find very much, mainly occurance surveys, a few seafood wholesalers, and reports of catch precentages.
It is also called both twolined tonguesole and fourlined tongue sole because it has two lateral lines on each side. The color is from light brown to dark brown on the darkside and it has a dark patch on the gill cover, underside is white. It is widespread throughout the Indo-pacific from East africa through Samoa including Sri lanka and India. In the Phillipines it is sold as the Dapa or Dapang. It is also found in the Mekong delta.
It is often sold as a food fish and used to make fish meal. It prefers warm water 26-29 degrees C. and while it will live in freshwater it won't breed there and stays healtier in brackish. it gets to 44 cm. and eats mainly inverts but will take small fish. Thats all I got for you Miles. To sell I think you would need some decent pictures of live ones in a tank. these pics are from a seafood company in Micronesia. I wasn't able to find any decent shots. The place I saw them for sale was in Oakland/Hayward, Ca. several years ago. They also had nice banded tonguesoles in full salt.
