Actually for now Dino shares a 20 gal tank (with a divider) with Chum Chum so its more like he has a 10 gal tank lol. How ever I am planning on separating them within the next month or so and ideally they would have a 10 gal tank each. I got very scared when Dino got sick or change his behavior n thought that Chum Chum could get sick too so it will give me peace of mind to have them separate. Besides since they are both males I don't know if they would want to be so close to each other lol. Regardles of the tank size I can tell that Dino likes it more when there is more plants around. Finally "fyi" fish is not a constant food in his diet actually nothing is constant in his diet i make sure he eats worms crickets pinkys fish and other small insects i get bored of food so i dont want him to get bored of his food =). Thank you all for ur advice n all sugestions are welcomed =)
