Came across this board while researching information for getting our Betta tank right. Figured I might as well join! Anyway, very new to aquariums, care, maintenance, etc. My daughter received her Betta as a gift and our current tank setup was gifted shortly after. It's a Topfin 1G. We recently added a thermometer and Topfin 10W heater. Will be getting another heater as this one doesn't seem to have a shutoff or temp adjustment and is getting the tank up to 83-84. We plan to get rid of the marbles and add a substrate suitable for live plants. We have so much to learn i hope our Betta stays happy and comfortable while we figure this out. Once we have a better idea of what we're doing I want to get him into a 10G setup with plenty of live plants. Anyway here are a few pics of our current setup. Any info and help is definitely appreciated!
