I have just recently been fortunate to acquire a mudskipper. It is an amazing creature, however I have limited knowledge on how to care for it. I currently have a 55 gal freshwater tank, but am not sure if freshwater is ideal for this fish. I am currently keeping him in a spare 10 gal tank I have filled halfway with freshwater. I also placed a couple rocks for him to sit on. Please help! He hasn't eaten anything I gave him in the past day and a half or so.
