I just put my betta Jack in his new 5 gallon tank (he's loving it) and I'm wondering which heaters are best for it. I live in Nevada so it's pretty warm here, but soon the temp will start dropping and I want to be prepared! He's my very first betta and I started him out in a 1 1/2 gallon bowl but now that he's bigger the 5 will be great! My main concern is that the water will get too hot, which will kill him. It might get too cold, which could also kill him!
Im calling upon on you knowledgeable fish owners for advice......thx!
Btw: I named him after Jack from titanic cuz eventually he'll die and float to the bottom. Morbid, I know, but what can I say, it suits him!
