man awesome pics bro! ure fish look lovely and healthy!!! RTCs have definitely grown since last time i saw them and ure water is much cleaner!!!! i think feeding them chopped up fish wud make ure water cleaner compared to feeding them live food for sure.
about the snakeheads...maybe cuz the razor sharp teeth screw up with he digestion :s thats why they spit them out? just a thought!
thanks for the links! i always enjoys ure updates!
OH and btw...ure PIM IS HUGE! never seen such a big one b4!!! how big can they grow (max size). i used to have one but he jumped into the tank filter and died
