So, my friend, who is new to fish and thinks he knows so much more than he really does, wanted an oscar for his 30 gallon. He goes to petco and petsmart, and they said he could get one, with room to spare for an 8 inch fish (only goes to show, petsmart and petco are stupid). But, that's not the worst part... He didn't cycle the tank. The 8 inch fish died in about 4 days (which was longer than I thought), so he got a new cichlid (which all he knows about it is that it is from Nicaragua). The oscar has lived 3 weeks so far, UNC (Unidentified Nicaraguan Cichlid). How long would you before the two die of HLLE?
