Well as ive had to get rid of my 4foot tank my mother said that i could get a new nice looking smaller tank for our living room just for the mudskippers and my mother loves them. so me and my dad went to Mastin moor aquatics and got a great deal on this Aqua-one AR-510 tank, its basicly 22"x24"x14" and looks great! I didnt bother using the trickle filteration and just used my mature aquaball. the mudksippers love it! and now im using my old mudskipper tank in preparation for my Gulper cat!
