Many people here have Betta's in 1-2-3 gallon tanks. That is fine by me as they keep their Betta's very healthy and happy. However, I like to keep my Betta Fish (as I don't have many) in bigger tanks like a 5-10g tanks or more.
I recently got as a gift a 2 gallon tank and thought to do a planted nano, but I thought about offering the 2g tank to one of my neighbors. Seems that the are interested in my fish, but don't have any of their own.
I have the tank, filter, but what I need is a heater.
I can't find a heater that is reliable. Some don't self adjust and some don't ever shut off. I don't want to give them something that won't work.
I can seed the filter and they can go and pick out a Betta fish :) I want their experience with fish to be good.
Can you recommend me a good heater for a hex 2 gallon tank?
Thank you in advance.
