How do you keep fantail fish?

Answer:
they only grow to the size of their tanks, so if you only have a small tank they will stay small. you need water treatments (one to equalise the bad stuff and one to add fish friendly stuff) and they will nip other fish and fan tails get nipped at my normal ones. they think the tails are food :)
fish look after themselves, just change the water
