Hello, Since I decided to set up my 5 gallon as a betta tank. I was wondering if I could possibly turn the 3 gallon into a ghost shrimp tank? I have since removed one of the plants into my high light planted tank and I would also like some ideas on some low light plants to put in there. Also, would a low flow in tank filter be to strong for them? I have sand substrate, is this ok to use? Also do they need a heater?
