The temp seems to be hanging steady. I turned the Vornado around and pointed it into the ductwork and added a second fan taking fresh air from the house and blowing it down into the water. The evaporation seems to be the key.
I added three female solarensis wrasses to the display and that seems to have filled the movement bill I was looking for. Now the male is out and about and there's pretty much constant movement all over the tank. Two of the chromis made it into the overflow, though, and have taken up residence.
How do they get in there past the gutter guard.
I've also taken on a challenge, though they aren't proving a terribly big deal. I ran across three juvenile Chaetodon plebeius. According to Michael: "The Bluespot Butterflyfish feeds almost exclusively on hard coral polyps ..., but also eats some filamentous algae.... Even though it is difficult to keep, the captive longevity record for this species is 13 years" (p. 174, _Angelfishes and Butterflyfishes_). Well, the fish are _young._ They have just started developing their blue spots and are probably just a little larger than a U.S. quarter. They ate Rod's Food, Nutramar Ova, and frozen cyclops yesterday within about ten minutes of being added to their tank and have little bellies on them already. I love Rod's Food. So, today is day 2. Aggression is already starting to be an issue with two mostly staying together and excluding the third. Once I get some weight on them, I'll have to re-home the third or move it to another tank in my system.
I've been sick today, so no photos yet.
