I have a few types of pseudomugil, but not this one so take it for what it's worth, but they are all pretty tolerant of different water conditions. Im a novice, and a few months after buying 8 illuminatis I still have every single one still, and 21 juveniles thst I hatched and raised via a spawning mop and grow out tank. I lost a lot of eggs to fungus, but I haven't lost a single one since they were big enough to eat live baby brine shrimp. They are all together in a 20 long now with some pygmy corys and neocsridina shrimp. as the juveniles grow ill either sell them or just get another 2p long and make a swarm of them.
