So for Christmas i got a 5.5 gallon aquarium wich was great. I cycled it, upgraded it from the crappy filter the set came with (i got an aquaclear 20 instead of the top fin 10 it came with) but the problem was I couldn't find a strong heater. I have a 10 watt heater in my 3 gallon and it keeps it at like 80-82 degrees wich my betta likes (he is spoiled with heat, if you even turn off the heater to change the tank he just lays on the bottom staring at you) so i just put my extra 10 watt in my 5.5 gallon tank. It keeps it at about 78-79 degrees wich is a little cool but my betta doesn't really seem to mind (i dont think atleast, I can't really ask him if he wants the water warmer) but the other day i saw a tetra mini 25 watt heater at a small pet store for like 27$ wich is sooooo much better compared to the massive 25 watt heaters for 50$ at petsmart! It would take some convincing to make my parents let me buy it but it is my money and I've been saving money it to get Yazi (the betta in the 5.5 gallon) something nice. So what do you think??
