I picked up this 55gal VERY cheap (I filled it, it does hold water) and I was wanting to to set up a brackish tank. I have fell in love with mudskippers they are the coolest things to watch! Does anyone know if a 55gal is going to be big enough for like 3 muskippers and a few (2-3) crabs? Is a 55gal even going to be big enough for the half land half water setup?
