Fishes!

Yesterday I went to the fish shop to discuss order and delivey of the Glassfish, and here they were, an entire tank with some ten Toxotes clearly Microlepis: just what I needed, once the glassfish had arrived (the idea was to get first the small fishes, so they could grow a bit before the arrival of the more aggressive Archer fishes). Anyway, I couldn't resist, also because it's the first time I see Microlepis here. So I decided to get the planned trio of them.
Choice: one specimen was clearly harassing the whole school, so I asked the guy to remov it from the tank, and kept observing: all other mates looked to get along pretty well, so I just chose more or less randomly.

Once at home, hurried ~80% water change (the tank was still full of NO3), lights off, and acclimatization: plastic bag about 1 hour in the tank, then started adding glasses of water tank into the bag (the water tank is still freshwater, so I assume no more sophisticated technique needed). Fishes appeared very quiet in the darkness. Even fishing them out from the bag resulted surprisingly easy, and didn't seem to scary them too much.

They spent the evening quietly moving around in the tank: two of them schooling together all the time, while the third more on its own. When a certain distance from the "school" was reached, he'd hurrily swim back with the others. I've enjoyed some amazing performance of sinchronized swim, with all of them in parallel sinking or raising vertically. Lovely.
