Glass knife of mine... i saw a picture of these guys on the first page but i wanted to share mine. Very cool fish, loves his glass chimneer until the NTT kicks it out and hogs it. Loves the plants, bloodworms and brine shrimp. I'd recommend them.
I try to bring in whatever oddball knives I can. Here's one of the most recent. Came in as 'thermometer knifefish'. Sorry for the bad quality, I had to take it with my phone.
