tough situation...
so, I recently adopted/rescued two angelfish, a swordtail, and a bronze cory from people keeping them in a 5 gallon tank. Now, they have joined my 29 gallon tank, and i think they are enjoying the space.

But i think I have a problem with the stocking.

I've got 8 zebra danios in there, along with a shoal of bronze cories and a bristlze nose pleco, plus the rescues. The danios are and have always been wild crazy fish, and fully utilize the entire 29 gallon. but when I read about the angels, and found that zebra danios were not a good companion for them, I started to get worried.

The angels have been here since saturday 9/1, and I think i sense some aggression between the angels. I was wondering if removing the zebra danios would help alleviate a bit of that?

i think i will probably have to trade with/donate them (the danios) to the pet store. i hate to do it, but the tank temperature is not quite right for the danios, and i know my family prefer the angels. i don't have another appropriate tank for the danios, and I know the 29 isn't perfect for the angels either, but i am hoping the two filters, and the addition of more plants (particularly floating plants) might help with that.

i like my danios, but i love the angels....but the danios were here first....idk. help?

The only thing that will help alleviate aggession between the angels is their ability to work it out, or removal of one of them, should that fail.

The zebras have nothing to do with it, and they are compatible with everyone else as far as temperature is concerned (low 70's). I have never once heard that zebras were in any way incompatible with angels. They are as ideal a community fish as can be imagined.

FWIW, the angels may be a pair in formation. Often this behavior can look aggressive. Or It may be they simply need more time to settle down. I think addition of driftwood & plants will help, as angels can be skittish if forced to live in exposed settings.

I would give it more time, and rehome one of the angels if necessary.

i thought i read in several places, including the angelfish profile on this website, that the angels and the danios were not compatible. but i'll look again. thanks for your input!

edit: okay i was right. the profile on this website says
"Not suitable with anabantids (gourami, betta), active swimming fish (such as danio) or small fish such as many of the tetras and similar fish..."

also, I keep the tank around 80 which is perfect for the angels and other members, but not so much the danios.

"...temperature 24-30C/76-86F..."

where zebra danio needs
"... temperature 18-25C/65-77F."

I won't speak for all danios. Celestial pearls would probably be eaten by Angels, and Giant Danios might be too non-stop active when placed with Angels. But since we were talking about temperature compatibility between Angels and zebra danios (e.g. "the tank temperature is not quite right for the danios"), I could not imagine an issue.

I think 80F is too hot for cories, also. Well, that type of cory.

djembekah 09-05-2012 03:01 PM

80 is like the top end...u.u ugh

Olympia 09-05-2012 03:03 PM

I'd lower the temp, honestly bettas are the only fish (that you own) that prefer temperatures up there. Angel fish seem to have a wide range, I'm not sure what they prefer actually. But 75F should be good..

djembekah 09-05-2012 03:04 PM

says 76 to 86 on here

i will lower it a bit though.

sidluckman 09-05-2012 03:05 PM

Check out some other sources for ideal temp for Angels. I know they do just fine closer to 70. Yes, 80 is high for cories, IMO.

I honestly don't think this is a worry.
I have bred them at high 70's, but generally kept them at 72-74 outside of breeding season.
