jewel tanks are about the best tanks you can get. they come with everything you need.....lights, internal filter, heater, just add sand and water and fish....lol...the heater sits inside the internal filter so keeps it looking tidy. I got 3 discus fish some black widows, albino algea eaters, bristlenose catfish and there babies, harlequins, rummynose tetras, cardinal tetras, lemon tetras, and clown loach.
Finally a topic i know quite a bit about...lol
also if you like neon tetras then i would get the cardinal tetras instead as they look almost the same but the dont carry neon tetra disease.....always quarrentine for 4 weeks before adding new fish or buy from a good dealer who quarrentines there fish. Need any help gimme a shout.
