Oh, I saw this PERFECT 4" crocea at the LFS that I LOVED! I wanted it so badly! Then I told my mom "darn, my tank has only been set up for 3 months!"
This makes me sad because it was just what I would want... It was so great...
Also, I thought it would be good to have because it sucks up nitrates, so I bought it, JK! I didn't, but I sure wanted to! Do you have to have a 6 month tank to have them??? Thanks!
