So I want to get into breeding fish and figured the easiest and cheapest way to get me started in the learning process is with guppies. I have a 29 gallon tank that I plan on using for this purpose. I just want to make sure that I am doing it right. So I'm not overly concerned with keeping all the fry alive, if some get eaten by the adult guppies in the tank it's not a big deal. We have a planted tank with some plants that I plan on putting in the guppy breeding tank. Jungle Val, Dwarf Sag, Water Sprite, and some type of moss, haven't gotten there yet. Substrate is my biggest question. I know that you are supposed to do a bare bottom, but I was wondering if I could do gravel or pool filter sand? Since I'm not concerned about keeping all the fry I am probably not going to separate the adults from the babies. I guess I'm looking for some general knowledge about the whole thing! I know from what I've read and videos I've watched it all looks pretty simple, but I'd like to do things right, not half-assed.
