My African Butterfly never leaves the top of the tank. I never thought of that. But I have seen my Crawdad hanging out at the top. Holding onto the filter intake, and I think plotting escape. I got this awesome creasture for $3 at my fish club auction.
I have a variety of shrimp and they are in various stages of thriving. My cherry shrimp population of hundreds crashed, and I lost them all in a couple of weeks. I have three Bamboo Shrimp. One large male, a female with eggs and a subadult. They all fan together, and once they were in a circle fanning, and sometimes they are in the coconuts, and only stick their fan out of one of the holes. That is really funny.
I have about 5 Amanos and they are lovely. I have a lovely mystery shrimp that looks like a ghost on steroids, with a thich carapace and a slight blue tinge. Bigger than an Amano and much smaller that a whisker. I recently purchased a tank of cherries and tigers, and there appear to be maybe 30 shrimp. I hope to breed them. And I have a tank of blue bees, but I don't think they are thriving. I was hoping to breed them. And this weekend I am trading some Bristlenoses for a few crystal shrimp, so I can try them again. We'll see. I haven't figured out why my shirimp thrive and then die out en masse.
Today I found rabbit snails and I was thrilled. Looks like their shells are mad up of tan mud. I am hoping they survive my acidic wate.r I will try to set up a tank for them. The store people let me take home the babies. Whee!
