Hello! Im contemplating to make my 20gal high tank a divided male betta tank. Im looking for a DIY divider idea and the best i found was using a cross stitch canevas with plastic cover bars ... but its not that pretty.. I came across this: Using mesh, u sandwich java moss in it, and use it as a wall. What do you think of this.? I will need to solidify the corners ( could be using the sliding reports bars) and maybe put one in middle to make it stand stronger... i found fiberglass mesh (rhe one we use on patio door) is fiberglass safe for fish? Will water flow correctly through the wall moss? Since i ll have 3 walls for 4 spaces of 5 gallons, but only one filter and one heater, so water would have to circulate correctly... im waiting for your thoughts on this ) Thanks!
