So I bought myself a 5.5 gallon and have decided to split it(originally it was only for Scrooge, however I rescued a betta from my cousin - Mr. Fishie). So I bought a separator kit(made for a 10 gallon but we cut it down) cost me $14.99(CND) + taxes. Then following a post on here about splitting tanks - went to Micheal's(a craft store) and purchased some of the plastic green sheets(the one that came with the kit is clear). We have opted to put in real plants(Moss balls on both sides and the other plant has yet to be decided). We are waiting for the cycle to complete before we put in Scrooge and Mr. Fishie. . .as well as the plants.
