It's rare that I name a fish but I've had my Trachy's a long time. First cats I had eat at the waters surface and they found the food as fast or faster then their tankmates who regularly eat at the surface. Between that and they're comical face and behavior I grew attached enough to want to name them. Unfortunately I've only decided on my females name, Black Betty besides her color there's just something about her that reminds me of that song by Ram Jam.
Most of our fish get names.
Our large Severums are named Sunny and Darkness, ones Black and ones Orangish colored.
The albino bichir is named Eli (as in "Eel Eye") because someone else in the tank ate one of his eyes. I think it was the African Leaf who has since been named @sshole because he picked on everyone so bad we had to move him.
