Sounds like my mate, keeps trying to give me advice when I know more than he does and he's the one been running a tank for a year, he has green hair algae everywhere bubble algae and red slime all over his tank added two corals both died he's lost four fish and about 30 or so cleanup crew! Then I try tell him how to deal with the red slime n stuff but he's like no every tank gets it eventually and its a bigger to get rid of, I told him it's the fact he used tap water and has NEVER done a water change says you don't need to!! Very ignorant and to top it off in his 55g he has a anthias, blue hippo tang, foxface, 3 cleaner shrimp, emerald crab, firefish, two clowns, lobster, and thinks he's adding a seahorse for his girlfriend next month. Really winds me up thinks he knows everything!
