Flounder Care Information
Well.....since there seems to be very little info about the so called FW flounder I am going to research the flounders lifestyle and eating habits along with its environment, in tern I hope to gain more info on how to raise a happy, healthy flounder,. Since I am an avid flounder fisherman I already know a bit a bout the flounder species. I live by estuaries, a sound, and the gulf (the first 2 are where flounder are usually found). I will be acquiring temperatures and salinity levels throughout the year in the sound and estuaries while
fishing for flounder.
I plan on setting up a seperate 20g FW and acquiring a juvenile flounder and slowly aclimate it to brackish between salinity levels varying from 1.004 to 1.015 to replicate the changing salinity levels in the estuaries and sounds where the flounder inhabit..since I have never heard about people doing this and soley for a flounder ill give it a try. I already have a flounder in my 25g FW but I plan on puting him in the tank soon to start brackish asap.
Some many reasons why beginner flounder owners end up with a dead fish a couple days later is because the fish doesnt eat anything or cant due to the fact there are other fish in the tank which get the food before the slow predatory like flounder.
Some feeding habits I have observed so far are.....they mostly like to feed at night. If you have a community tank make sure your other fish are fed well before trying to feed the flounder! Keep in mind that flounder sneak up on their food (prey) then snatch it. Since most flounder acquired are juveniles (babies) they have very, very small mouths and need small
foods, preferably small live foods or frozen, they will take flake but it will take time to get used to. Some foods you could feed your flounder include various worms species, small crustaceans, mollusks, and small fish as of now im feeding mine frozen shrimp not brine but the kind that are used in shrimp cocktails.
When you feed your flounder make sure he isnt sticking on the glass ( which they like to do, like a pleco) because they cant reach their food. Make sure hes on the substrate which should be SAND!!! not gravel because it can cut his soft belly. Put the food about and inch away from him (you literally have to cater to these fish since the other fish are always noising around tryin to steal whatever food is around) when feeding larger portions use your finger to make a indent in the sand and put the food in there so the flounder can glide over it and eat it, If you dont he will have a hard time trying to swallow it because its on level with him, remember they hunt their food.
When you have placed the food near them sitback and watch closely most of the time theyll eye it. Then they will slowly hop towards the bait. Their gill movement changes from normal breathing to slow, still long breaths so they can look sneaky. The flounder will then move closer then capture his prey happily devouring it....their stomach is located behind their gill after they eat youll see a bulge there.
So far this is all the information I have acquired and I hope to learn more about this mysterious fascinating fish so I can help others who wish to keep a flounder as a long companion.
Are your eyes hurting now
, so i got some flakes down near them. No clue if they ate. Seem to be doing ok this morning though.
