Choosing
How to pick from this list
- Start with your water. Test pH and hardness, then keep species that already suit it rather than adjusting the water.
- Plan for adult size. A fish that is small in the shop may grow large. Check the minimum tank on each profile.
- Buy the group, not the single. Most of these species are shoalers and settle best in the numbers shown.
FAQ
Common questions
How many of these can I keep together?
It depends on tank size, filtration and the species’ group size. Use the tank volume and stocking calculators, and add fish gradually.
Do these species need a heater?
Most listed here are tropical and need a heater. Cool-water species are marked, and suit unheated tanks in a warm room.
Can I mix species from this collection?
Often yes, if they share water and temperature needs and neither is aggressive. Check each profile’s tank-mate notes first.
