Well, thanks for the good wishes, but it looks like the aquarium can't take them in. They're short-staffed, and apparently no one really knows what the future plans are for the freshwater tank. Although the biologist did tell me something that made me less eager to donate my clowns. I asked what would happen to their own clowns if the aquarium couldn't keep them, and she said that if they couldn't re-home them they'd euthanize them. I don't know--maybe I misunderstood her, so don't quote me on that. But I definitely don't want my healthy clowns to be put down because of renovations on the aquarium tanks.
Anyway, this whole experience is making me very angry at the clown loach trade in general. I mean, granted, it was I who initially bought my first clowns without researching them--but it was the lfs employee who told me they'd be "fine" in my (then) 20 gallon tank. But nonetheless, there are large numbers of clowns at all the area lfs's. New shipments arrive all the time. Are all these clowns going to people with 125 gallon tanks? I doubt it. Why is the industry trading so heavily in a fish that has such demanding care requirements? I'm having enough trouble finding
one person with a suitable tank for my loaches--I can't stand to think of the thousands others that I bet enter Oahu every year who live short lives in inadequate tanks. Or, die of ich right there in the store. While looking clearly diseased and still being for sale, I might add.....
Sorry for venting!:mad2: I'm actually not too upset by the aquarium's rejection, I guess.

I'm not in urgent need of re-homing my clowns, so I have time to keep looking for a new owner. I think my next step will be to try and send a group email to the Honolulu Aquarium Society and to the list-serve hosted by one of the best local lfs, Coral Fish in Aiea. I'll send along an update if anything new comes up!
