Hey everyone!! I'm new here, and I signed up just to get opinions lol. So I set up a 75 gal, tank dimensions: 18"L x 48"W x 21"H, and I'm a big dino enthusiast. Currently in the tank I have 3 Convict Cichlids, a Red Devil, a Belly Crawler Pike Cichlid, a Pleco and 2 goldfish that have grown too big for the pike to eat. In your opinions, what would be a good addition for the theme or is my population count at a max? Gars are obviously too big, as well as Arowanas and Lungfish.
