From our collective of glowlight tetras (Inky, Blinky, Pinky and Clyde) it appears that Clyde has passed on. (Actually, the collective was named Inky, Blinky, Pinky and Clyde... not sure which was which, so Clyde is the first name retired. I'm such a bad fish-parent). For a while I thought that Clyde was possibly a female with eggs, but it appears it was just dropsy, which affected Marty (our betta) as well. I think I need to change the water more frequently in the tank as dropsy can be triggered by poor water quality, and I've had some pretty poor water quality in that tank. I'll spare you all the 'circle of life' details that our plecostamous (Plucky) did, but suffice to say I hope he doesn't start having issues.
