This is why I am moving them to my other tanks. Wouldn't really say that corydoras need at least 6 to be healthy though, since I have had them for around a year without any heath problems. They also rarely shoal.DutchAquarium said:
Guppies here are quite expensive (males are $4-5 each, and females are $3), so I think I'll just start with a few.DutchAquarium said:you could do the guppies, start with 10 because they will boom later. Your going to see more of a shoaling group at night and 6 is to give them their security.
