Schooling fish?
 

I have a 70 gallon aquarium and was interested in adding 3 or 4 small fish that would school together.

I have heard that in "smaller" tanks they usually will for a while but then they stop if there is no predator present.

Anyone have any ideas what would be a good choice for this... if it is worth it?

Green Chromis are nice schoolers. Pretty inexpensive too!

Banner fish also like to school alot bigger then chomis tho.
like the size of your hand.

But should be noted they are not reefsafe.

I thought green chromis but I heard they start killing each other after a while.

Anyone had purple chromis?

I require reef safe fish only.

Oh I really hope not I have 6...

Hey
 

What size tank... and how long have you had them? Do they school for you?

I've always used blue/green chromis to school and draw out the more shy fish...they're an excellent dither fish (similar to rainbows in freshwater) never had any problems with them. There'll be a school of 6 in our 75 at the shop

Green chromis are awesome, i had 5 in my 90 one disappeared but I have had 4 for a good 4 months, and they are awesome they are normally all in a group, especially if they see people outside of the tank they will all group up. Also they always stay at the front of the tank where everyone can see them!

+1 on the Chromis, excellent, I have had 4 in my tank for the past 5 yrs..still swimming together.

52 Gallons I have only had them for a few months now. When I had 2 they hid most of the time when I added 4 more they swim in the open all day long. Can't say anything about habits as they get older.
