How many fit in each tank?

The largest group where none died in 90 days. Tap water · coral sand · bacteria starter on day 1 · fish added on day 10 · 25% weekly water changes.

It likes hard water (high pH and hardness). This was calculated with coral sand to harden the water.

Good tankmates

No eating or bullying either way, with plenty of overlap in temperature and pH. Fish that swim at a different level come first.
