Damsels in 75/150 gallon tank

[jrobison]

I know they become aggressive, but does anyone have experience keeping several in a 75 gallon tank with long term success or do they end up killing each other off? Like maybe 10 blue and 10 4-stripe. I'm also thinking about adding several to a 150 gallon tank I maintain at a hospital. It needs some bright colored, hardy, cheap fish that move a lot. What are the chances of success like this? Both tanks have quite a bit of live rock.

That's a lot of damsels . . .

I've got a trio of azure damsels in my 65, and with three of the to bounce off of, they keep their feistiness to themselves, and rarely bother anyone else with their shenanigans.

If they were to be the only fish in the tank.... then maybe.. but still probably not at those numbers..

I have 3 saphire damsels in my 120.. I had 4 and there wasn't enough territory for more than 3...

Yellowtail damsels are docile compare to other damsels. 4 stripes r very aggressive.

If you went for something like springers or allens then I think you'd be OK for groups. I have a 48x8x8" (that is meant to be inches) with five allens and they are happy as anything. I had a pair for a few months then added a trio and they didn't even scrap. Springers are very docile as well and so are Talbots. I think you'd be fine with talbots and springers in the hospital tank and they are colourful.

I have 2 x 4 stripes in my 125 and there not aggressive at all. In fact my 2 firefish are more aggressive then my damsels. (I may have just gotten lucky and got 2 docile damsels)

How long have you had them?

A year give or take a little.

Thanks for all the info. I'm more interested in doing this in the 150, I'll look into some of the more docile ones mentioned.

I think Damselfish got a bad wrap because they are too often kept as singles. In my experience, if you keep the smaller species in pairs, they will be too busy with each other to care much about the other fish in the tank. Only fish that are known egg thieves get kept at bay. Especially the smaller Chryspitera and Pomacentrus species should be fine with the right tank mates.

Of course a fully grown Dascyllus may not be fun in any home sized tank. I had a trio of D. trimaculatus of which two were fully grown (~5"), spawning adults and they were no fun even in a 250 gallon tank.
