Ok, well seeing as I lost 2 fish my red devil now has the tank to him self, or though he is loving the space of 100g its going to be short lived as my Midas is comeing home tonight and is going in that tank but divided! as these 2 fish hate each other and fight when ever they see each other i need a stong divider that will not fall over or else all hell will break loose! What should i make it out of?
http://www.gcca.net/howto/tank_divider.htm I'm cheap & lazy, I just cut it a little larger than the inside of the tank. It works for angel pairs, bigger cichlids would bash right through it.
Honestly my idea would require the tank to be empty. I would silicone strips of plexiglass to teh tank as guides with just enough room to fit a piece of half inch egg crate, or possibly in the case of your fish milk crate.
