My betta is in a 1/2g bowl and I can't seem to get the temp above 74 or 75 degrees and right now I just did a 100% water change and put him in one of those holding containers that lps use when they scoop fish out and put them in their before they bag them and I set this holding container in my 10g that has a heater and his came out so cool and he is swimming a little faster in this holding container. He really seems like he likes the warm temps and he also seems likes he wants to be in their but can't because their are red eyed and x-ray tetras in their. Is their a way to raise the temp in his fish bowl to 78? Oh and the fish bowl is temporary until his fins completly heal.
