Well, i've just harvested my triops that had grown very fast! I put one in my tropical tank and there was a fight between my head + tail tetra, but 'big momma' my massive head + tail finished it off in about 30 seconds and them I put one in my brackish tank with my Figure 8 Puffer and he went mad!! He ripped it too shreads and loved it!! Took him about 20 seconds to complety destroy and eat a 1-1.5" triop! (the biggest I had) Plus, he had to chase it first which was great for me to watch and great fun for the Puffer! Really good idea to grow your own triops/sea monkeys!
