Chromis - Howmany ina 210?

[bignick]

Hi,

I see you have Blue green chromis dirt cheap on your site and iwas planning on adding a school of them to my 210. I have lots of rock ad plenty of hiding spaces in the tank. How many would you suggest to add to my 210?

Thanks a lot,

Nick

I mean in a 210 you could easily do at least 25

bignick,

Thank you for contacting us with your great question. When deciding how many fish to add in your aquarium the basic rule of thumb with most aquariums is one half inch of fish per gallon, keeping in mind the size they will grow to. We typically recommend between 5-7 although this will depend on the other tank mates you have. They can grow up to 3”. They are a great addition as they have a lot of personality.

If you have any further questions please feel free to contact us at 1-800-334-3699.

I think its good to add atleast ten. Chromis have a bad track record in small groups in the aquarium. They will usually pick each other off one-by-one if the agression is not widely dispersed.
