what fish will school together. i know cardinals will and yellow tangs will but i was wondering what else there is. i had a costomer ask me the other day and i cant stop thinking about it.
The most commonly seen school of fish kept in home aquaria are the green chromis. Most people keep at least 3 or more together and if your tank is at least 75 gallons they will school back and forth across the tank. They will stick together in smaller tanks too but the schooling effect isn't as good.
