Sand is not the best substrate for tropical fish. It's great for salt water fish though. You do have too much gravel and it looks like your heater is on the left end and the filter return is on the right end. The heater is too far from the highest water current area of the tank and you will get uneven heating if I'm seeing this correctly. Try to move the heater to center or toward the side with the filter return tube. This will distribute the heat more evenly.
Other than that....Beautiful tank but even prettier Betta. He is absolutely adorable.![]()
Thank you, I will definitely do that. I have the thermometer at the opposite side of the tank, in between the filter and the heater and it is reading 78, so hopefully that is accurate as far as the tank right now. But I will move it when I get home this afternoon.
On a lighter note, does anyone have any name suggestions for this little rockstar? I can't think of one
