Stocking a 20 gal tall.

[Curt Boswelll]

How many blue-green chromis can I keep in a 20 gallon tall aquarium with a pinkbar goby, Randall's pistol shrimp, sexy shrimp, and two red neon eviota gobies?

And how many without the two eviota gobies?

I would only do one in that size tank, they would probably turn aggressive with each other fairly quickly with the confined amount of space. Maybe 2-3 small fish total in a tank that size.

+1 on the single chromis. Just out of curiosity, what is your reasoning for wanting the chromis?

 

[Curt Boswelll]

I like the color of it. And wanted something that wouldn't be burrowing in the sand.

 

[Martini5788]

Ok. Be sure that you qt the chromis, look up in the disease forum the specific qt and treatment for uronema.

What about a pinkbar goby, one blue-green chromis, and a midas blenny or a tailspot blenny?

 

[Martini5788]

Midas blenny are too active for a tank that size, it would go crazy in a 20 high. I have a tailspot and I really like it. That would be a good choice.

 

[Curt Boswelll]

How would the one chromis do with the pinkbar goby and tailspot blenny?

 

[Martini5788]

I'm gonna be honest with you though, I'm not sure chromis is the way to go. I don't think the 20h has a big enough footprint, if I remember correctly it is about the same as a 10 gallon right? My chromis is very active and uses the entire tank, and I have a 4 ft tank. I would post in the please check your purchases thread with snorvich and see what he says.
