A pic of my tank currently: (the plecs fav spot is actually inside that rock to the right, and he comes out at night to scrub around. View attachment 1233423
Thank you, my GT is my favorite fish I've had. He's always been so calm with others, yet still is pretty territorial and will chase around others. He's always out and about in the middle, and the coloring on the bottom of his chin is really starting to intensify as he grows. (I got him when he was just about 1.5 inches long)
A group of SAE's would be good in that 75. I had mine in a 20 long too, they do need length in the tank. Very fast and active fish when in schools and eats more types of algae than pretty much anything else. Full sized ones probably wouldn't get eaten.
