Celestial Pearl Danios and Guppy, compatibility

Granberry

I have a 15-gallon bowfront tank that houses 14 Celestial Pearl Danios. It is a planted tank, but even with the plants and fake driftwood with lots of hiding spots, they are very shy and skittish.

Lately, my guppies have been having lots of babies, so I have been moving the fry to this CPD tank until they reach a decent juvenile stage and then moving them out. This hasn't seemed to bother the CPD because they stay at the bottom and the fry stay at the top. However, I have decided not to let these guppies have any more babies and have decided to move the (single) male out of the tank. Can I put him in with the CPDs? Will he nip them or otherwise stress them out? I know CPD do best in a species tank, and that's what I've had them in, but will 1 male guppy be an issue?

A lot of this depends on the nature of the fish, some guppies can be very shy and hide constantly, others can be teritorial and chase everything in sight, try him out with the fry but give the fry a few hiding places to shelter in, keep an eye on him as agression will show relatively quickly.
guppies are not agressive, but I have had a couple that love chasing and bullying smaller fish. It's all part of the pecking order in a tank, but I can't see any serious problems though.
Let me know how you get on

I wuld agree, observe carefully as the trouble could go either way.

BTW, you do realize that removing the male will not end your guppy fry for several months? Once impregnated, livebearer females can delive several batches of fry without a male being present. Just so you know; check the profile.

Hmmm, well, I knew they had the ability to access what they needed to fertilize eggs for a while (super something) but I didn't realize (a) it would be several months or (b) that they would, just because they could. But oh well, my LFS will take them and I have room for any really pretty ones. Thanks for the info!

It can depend upon the individual fish, but the capability exists.

Shewbert, you asked for an update, so here you go: I put the male guppy in, and so far, he hasn't annoyed anyone. He stays near the top with the fry (and my fry are all still there; they're really too big for him to eat) and the CPD stay at the bottom. I sure wish I knew a way to get them to swim about more. I'm currently tweaking their water chemistry, so maybe that will help.
