I have a 10 gallon tank that is currently occupied by a blue eye, an endler (guppy) and 3 bumblebee gobies. They are currently quite happy and yes the tank is slightly brackish. Right now I have 2 pieces of driftwood and some small pebbles as decoration. I am considering changing the setup of the tank and I was curious as to what fish would be appropriate for a 10 gallon tank. I am VERY attached to the bumblebee gobies so I prefer that they stay, but the blue eye and endler I could move. I was looking at a mudskipper but I've gotten some conflicting information as usual so if anyone has some sound advice on keeping mudskippers it would be appreciated. Thanks in advance for all your help!
