How many blue chromis should I get?

[phi delt reefer]

common misconception of reef tanks - getting a lot chromis won't mean they will school together - schooling is a survival instinct in natural reefs against predators. Unless you a get a predator in there they wont school but instead they will get territorial and start playing "survival of the fittest". They work together when there is a threat - when there isn't threat its every fish for himself.

They might swim together for a bit in the beginning but unless you have a giant tank you will be left with one in a couple weeks/months.

Guaranteed in a 55, they will kill each other off until there is only 1 left.

save your money and buy one.

Or, if you really want some blue, go out and get yourself a couple blue assessors...

a little more expensive, but a peaceful community fish with a wow factor to itl.

Thanks for the advice everyone! Those blue assessors are really beautiful how many of them could I put in? I've decide not to go with the blue chromis lol

I have 3 and they don't school, they do chase each other tho

I have 2 in a 40gal tank they dont fight each other but they do stay around each other when the clowns start to pick on them.

it's worth mentioning how long you have had them for IMO...
