I have a NanoCube and the "Ruler" is a big planking pleco, who likes to plank on the ornamental columns. I've kept aquariums since I was a kid and I'm always happy to find and support a family run store nearby, like Paradise Aquariums in Queens.
In my lifetime I've had two swordfish jump that I can remember vividly - one landed on the heater vent and mummified before I found him, the other turned up tangled in the tassels of a bedspread. Yours may have flipped his way into a crack in your floor? Sorry for your loss, but as the saying...
Request Help - I am wondering what this is and how to treat it. Or should I leave it alone? Thanks for your help.
