newbie, advice/comments appreciated :)
Hi, I'm a complete newbie to fish keeping. I've recently bought a 20gallon/90 litre tank and have it set up with sand as the substrate,and the heater and filter that came with it (aquael internal fan 2). I started the fishless cycle 4 days ago and it seems ok so far, my ammonia went from 5ppm to 1ppm in 3 days and I topped it back to around 4ppm today. The water went cloudy a while after adding the first ammonia but is now ok,
although when I use the air tube thing (sorry don't know name) on the filter to make bubbles the whole tank fills with tiny bubbles and looks dirty, which I first thought was my sand being messed up.. so I've turned that tube off, will the water movement from the filter alone be enough? Do I need an air pump/stone?
My main question is about stocking, but if I've said anything that sounds wrong I'd appreciate being told. So I've used sand as I really want corydora. I was planning on 6 of a small species, maybe 3 trilineatus and 3 panda. But the book I have said they're not good first fish as the tank needs to be more established. So I was thinking of 5 or 6 harlequin rasbora to start out (after cycling), and then the corys, but I would also like a little school of neon tetra.Would that have me over stocked? Is my tank too small for the corys?
Water parameters before starting cycling were ph 7.2, GH 16, and my nitrates in my tap water were pretty high, about 30-40 :/ they've dropped a lot now in the tank, don't really understand why? But I plan to have live plants so I hope that will help any nitrate issues, and if not I've bought a thing to attach to the taps to remove nitrates.
Thanks for reading and any comments/advice are very welcome :)) many thanks.
