I also love aquarium fish. I had them since childhood. However, such enormous was not. Mostly barbs, angelfish, swordtails, guppies, a couple of kgs (one that is poisonous, whether the current beat), the Golden fish. Separate from the living fish only know betta.
I can always help, consult and tell you everything about the aquarium :)
As soon as the opportunity to make at least a small aquarium to ask for advice)
