I'm looking at buying a 29 gallon tank in the near future. I'm going to get a Aqua clear 50 filter for it and probably a stealth heater. I would like to hear some advice/opinions on stocking, gravel and plants. I have 2 buenos aires tetras and 2 zebra danios right now, in a very small tank. I will move these guys into my new tank to start, but would like to add more. What I would like to do is add 4 more zebras and buenos, plus 6 silver tipped tetras and 1 otto cat. Does this sound like to many? As far as plants, I figure to start with 3 or for java ferns. What would be best for these plants gravel or sand? I've heard anywhere from 1lb of gravel per gallon of water to 2.5 lbs of gravel per gallon of water. What's the right amount for plants? Thanks.
