I keep a lot of Buccochromis type and I can say 1 thing about all of them, they are extremely active fish! They swim non-stop, up and down, and all over your aquarium. They are generally a little bigger than your typical peacocks and some haps, reaching 8-10 inches easily. They have a very unique head, making them very easy to identify a Buccochromis type fish.
The Buccochromis Nototaenia is no different than any fish in the Buccochromis family. Same head shape, and super active. They grow very fast and usually will eat anything you put in the tank. They like sand substrate as for most fish since sand is their natural environment. Please provide a big tank for them, they like open water where they can swim freely. Decoration is not important because they are roamers, and prefer swim space more than anything.
They are piscivorous, which means feeding on smaller fish. But in an aquarium they will eat anything. Remember to give them high quality pellets with rich protein and sometimes a veggie base pellets so they get all the needed nutrients.
They are not really aggressive at all. Both the Buccochromis Nototaenia and Buccochromis Spectabilis I have are not aggressive. They tend to get along very well with other fish, just keep an eye on smaller fish since they might end up on the menu.
Unlike the Buccochromis Spectabilis which primary colors consist of just blue and yellow with orange marking on fins, this Nototaenia is extremely colorful. See the pictures below.
