I have always kept arowanas. Since my big one had a terrible accident, I now have a baby aro so I was finally able to get CL's. I have 3, maybe 2 inches now. They eat everything, but do they have any special diet needs? How will they fare in black sand? They get along with my baby aro, so I hope they grow together. Is there anything special about the proper keeping of CL's? Man, they are sooo darn funny, I nicknamed them The Insane Clown Posse.
