I only read the betta article. I think it's very good and more people should read it, the only thing is filtration. Two of my bettas died of exhaustion due to the filter being way too strong. Our third boy was better, we kept him in the same 10 gallon but with gravel and hides and plants and a heater and a lamp on durring the day. We only put the filter on for 10 minutes a day. Are there filters specifically made for less strong swimmers I can buy? Actually Illusion was thriving, sharing the space with a dwarf pleco til my dad actually put two feeder goldfish in the tank WITHOUT QUARINTENE that were "too pretty to feed to my snakes" and since my tank was "not built up or important enough" he thought he could come to a happy median with a cool water fish and a tropical fish.

SORRY, THAT WAS JUST A RANT
