Hi, Couldnt help but reply to this one! the neon tetra thing suprises me ive used Neons b4 to cycle a new aquarium with no problems whatsoever! not to be confused with cardinal tetra of course which are much more sensitive. Ive also found Glowlight Tetra very hardy. Other hardy first fish include white cloud mountain minnos and danios. You shouldnt get any smell from an aquarium ever if you do its probobly Ammonia, Algae (on bracing bars etc.) or spilt fish food inside the lid etc. Introduce 5 or six small tetras to begin and feed sparingly. Monitor ammonia and nitrite levels and add fish on a fortnightly basis if levels are zero! Add a few fish at a time (every fortnight) so as not to encourage ammonia/nitrie spikes! Have you seen the new Tetra product ? safe start! works on the basis that Spirobacter are now regarded as responsible for the conversion of ammonia and nitrite and therefore introducing a live culture allows you to stock your aquarium immediatly!
Have fun
