Yep, temp stability is huge. I run two heaters in my 30-gallon just to be safe. Also, check for aggression—male guppies can be relentless with each other.

Glad you caught the issue when you did, that's the key. I've found that torches generally need some space from hammers and frogs, but hammers and frogs can get along just fine. Usually, it's not a problem between those two, but it's always good to keep an eye on them.
