So I fed Calder and Anael tonight. Calder managed to splash his pellet over to the corner of the divider. All is well, fine and dandy. And then BAM-- he lunges, and wiggles through. I was right there. and I grabbed a cup and got Anael out before he even realized he had a guest. Calder runs like hell from the cup but Anael just come to investigate and get swooped up.
I'd thought my divider looked a little gappy before, but it held up fine. Needless to say, I trashed that one and re-cut with a bit more divider left. Got the bowed look going on but oh well.
Since i was thinking about heading to petco tomorrow, I cut a second one too, and divided the tank into three parts. It's looking pretty spiffing with, aside from the empty middle section. The dividers aren't quite evenly placed, but I suppose next water change I can fix that-- pesky gravel just gets in the way. lol.
