Scroll down, "gnunance" posted pics of a beauty and "dk66gt" posted pics of one of the best Ive seen in awhile. As far as info goes, Google Amphilophus Trimaculatus on the internet and you'll find enough to get you started. They are very territorial, do not generally accept tank mates and males get about 14 on average +/- a couple of inches depending on how you care for them. Trimacs are one of the most aggressive Ciclids around, To mix one with a Dovii IMO is asking for one dead fish unless you have a huge aquarium. 100 gal isnt close to being big enough for them both. If you really want a Trimac get rid of or re-home the Dovii and put the Trimac in the 100 buy itself. This is a fish with a bad adittude.
