I am new to the group. Have had our betta since June. As the weather has cooled down alittle here, I have started shopping for a heater.
He is in a 2g tank.
From what I have read for the last few days on recommendations on this site, I am going with the Hagen Elite 25watt heater.
But when looking on Amazon, there are 2 types, both mini, both 25watt, one is preset but reviews show it is adjustable, the other is a thermostatic one.
Which one should I get? I want one that is temperature adjustable and wondering if the thermostatic one is adjustable.
Does anyone have this one?
Thanks for reading and looking forward to feedback so I can order one for our Mr Red Fish :)
