Re: That was very resourceful and wise, using (none / 0) (#3)

It would seem that only three of the males are hanging on the bottom of the tank now. The rest have perked up and started meandering around in the middle areas of the tank. I was looking at the three on the bottom, and they indeed have the very largest of tails, longest top fins, and are significantly more curved than their fellows. Their body length is also larger when compared with the juveniles. I'm thinking you're right, siops, and they are the oldest in their group.

I've been going back and forth now, trying to decided on leaving them in the new tank, or putting them back in their old tank. Since I've just done a serious overhaul of the old tank, I don't think that water would be particularly any better for them, so I'm leaning towards letting them be on the bottom, wetting some food for them, and seeing if they don't perk up eventually (like the handful of others have through the afternoon).

On oxygen: With the sludgy state of the old tank, I would honestly guess that my community tank has a higher oxygen content. There was a long bubble wand generating a super-fine misting of bubbles in the old tank (and it's still there with the mixed group), but I though that the bubbles don't really do much for the oxygen content of the water? (I thought it was all surface area contact between air and water that increases the transferrance of oxygen, and the speed and surface area of the bubbles created only minimal increases along with churning the water more and the top surface area having slightly more air contact.) Or, does a fine mist of bubbles actually do something more than look pretty? In which case, I've got some more installation to do!

oxygen in tank water (none / 0) (#5)

It's nice to hear that some have recovered already! Well, it is unclescott who told me about older guppies having a harder time adapting. =) (go unclescott!!)

I think they're better off in your community tank, because if you do transfer them again, they have to adapat again... and that's stressful.

About that bubble stream, you're right about the surface area contact on air that increases the oxygen in the water. I've read it on guppyinfo a week ago. They said that the stream of bubbles contributes only a few on oxygenating the tank water, that it's more on the surface contact and circulation of oxygenated water around the whole volume of the tank that's more important and helpful. Here's the link to that topic. http://guppyinfo.com/index.php?option=com_content&task=view&id=57&Itemid=23
