Hi i am currently saving up for a bigger tank like a 3-4 footer and was also thinking about getting black ghost knife fish. But i need to know if it would be friendly to my fish? i have 2 dwarf gourami, 8 tiger barbs, 3 rosy barbs, 3 volcano rasboras,2 albino kribensis, 1 male bristlenose and about 5 baby ones, 2 dwarf loaches and 3 kuhli loaches.
