I think the tank should be cycled by now Ive had it running for about 8 weeks now and had been slowly adding fish during that time. When I started it I placed all the hardware and gravel first then the next day i added the plants and on the forth day I added 3 neon tetras, and then gradualy added the other ones. I replace about 10 galons of water every week. And so far all seems well The only casualty so far has been one neon, which was apparently dead on arrival as I noticed this soon after getting home and placing them in my aquarium bucket for aclimatization..
As far as getting another tank I dont think I could for the time being..Id love to though but this time a much larger one. like a 55
gal breeder or even something in the hundreds of galons range....
