^ Thanks for the comments, and i'm glad to see this project of mine has inspired you to do a planted tank as well... so be sure to hit me up with a link when you post a thread...
As for the Needle Nose Pikes, they actually do okay with the Clown Killi's... mainly coz the Pikes literally will only stay at the surface of the tank, where as the Clown Killi's tend to be surface to middle level swimmers, so can't say i've seen any problems thus far between the two?
But i definitely agree, they do look like really cool little monsters... especially fun watching them attack flake food...
