mine went from 1.5 inches to over 9 now since November 08 in a 265 gallon with weekly water changes and a VERY varied diet of market shrimp, mealworms, earthworms, crickets, cichlid gold, bloodworms & cichlid sticks.
He is the biggest pig of an eater of any fish ive ever had and will try and take every drop of food I put in the tank, which has made me spread the food from one end of the tank to the other. He has eaten three 5" shrimp in one sitting, before I figured out the best way to get food to the others.
He has been aggressive since I got him and only quit harassing everyone once I put my bigger male festae with him, but I have a felling, with the trimacs growth rate almost double what the festaes is, the trimac will be the king of the tank again by summers end, unless my dovii grows a pair and defends himself.
