Hi Lioness.lioness501 said:does it need to b a big tank
just because they come from freshwater, they are brakish inhabitents, so to ensure that they live to the appropriate age and stay healthy, they should be converted to a brakish tank. They should be slowly acclimated to the brakish water. Dont go and change from fresh to brakish immediately. You should slowly increase the salinity as not to put them into shock. Most brakish inhabitents can be converted to freshwater, however, as previously stated, they will not live their normal life expectency....that is all true for the most part they are super easy to take care of I have 3 of the little guys they are fun to watch
. they do not have to have brakish water what ever you buy them in thats what they should stay in.
