El Yay!!

Momasquito (my female mosquitofish) decided to drop last night. She dropped a nice even 16 fry. Its interesting because while trying to catch these little devils I noticed they were larger and a whole lot quicker than guppy fry. Evolution:)

Kudos to you for giving the fry shelter and mom (none / 0) (#1)

a lot to eat. Eastern Gambusia are notorius canibals. By the way, she really had 24. ;)

You've already noted one reason why it's not wise to keep Dambusia with guppies.

And yet Gambusia and Heterandria formosa, somewhat inaccurately named mosquito fish and least killifish, are found near each other in similae habitats. The Hets are even further into the vegetation that the Dambusia.

The NANFA national convention will be in Columbia, SC in about three weeks. They have quite a line up of speakers and a bunch of collecting trips. Those livebearers will very probably be among the fish collected.

Wish I could be there. :)

Interestingly enough, the female wasn't at all interested in making a meal of her fry. The male in the aquarium was going nuts chasing her all over the aquarium while she was giving birth. The entire time I watched she never ate a fry and he seemed to not even notice they were there. I probably did not get them all...but 16 of those "Dambusia" are plenty for me:) I believe I'm going to let these fry grow a little larger and then release them into a 10 x 14 foot pond where I work. I can't find any reason to keep them as common as they are. I made a stop at an LPS and found 5 of these guys. The shop owner didn't even know she had them.

Can they get from the pond into the local (none / 0) (#4)

streams? That may not be desirable if they are not native to the area. (Bet the pickeral would still know what to do with them.)

Aside from upsetting an ecological balance, there is some danger ofcarrying aquarium pathogens with them.

If the pond had no fish and wasn't likely to drain into the local watershed, that is probably a good thing in this age of mossie carried diseases.

The common Gambusia are sold as a biological control in the Chi-town area. The assumption is that they will die off with winter. That doesn't take into consideration power plant cooling ponds and places warmed by industry released water.

There are reproducing populations in the Cleveland area and by a local nuclear plant. So they sometimes even hang on at a latitude quite a bit north of you.
