He looks like he's going to be super pretty! Please keep updating photos as he matures and his colours and fins develop, miss seeing that from when I raised guppies!He's like my dwarf gourami, when he sees anyone walking past the tank he comes up and starts patrolling the surface like he hasn't eaten in ages. Just want him to get a bit bigger (larger) before I move him out of the quarantine tank. I'm starting to think he'll need some friends though, from what I read guppies do better in numbers. I'm thinking a couple of other males, as I don't want them breeding.
Yep, male only guppy tanks can work. I have five males together now who get on just fine. There is very occasionally a super driven to mate terror who bullies and can't live in a male only tank, but in the hundreds I raised, I only had a couple like that. Had a tank of 30 odd young males who were absolutely fine together - except for one who was a terror and had to be separated because he was a demon to the other males. But on the whole, most will sort out a pecking order and then settle down fine together! Plus you get all the pretty colours and fins with the males, and without the hassle of constantly raising and rehoming fry
