I am assuming you know about cycling a tank. If you don't It sounds like you are going to cycle your tank with fish. This is the way I started in the hobby, but many folks think it's cruel and prefer to do a fishless cycle. If you choose to cycle with fish, I would start with the platies and get a good master test kit like the one Aquarium Pharmaceuticals makes. You are going to have to do a lot of testing during cycling to make sure your fish don't suffer and die from ammonia or nitrite toxicity. I would not add any more fish after the platies to the tank until it was cycled, and the corys would be the last ones I would add.0morrokh said:I'm getting black mollies, female bettas, and cory cats fo my 10-gallon tank (yes--I finally decided! ) Once the tank's ready, would it be better to get the mollies or the cories first? I've heard they're both pretty hardy.
I have my corys in a tank with regular gravel and have never had a problem. I have read a lot that sand is preferred, but mine seem to be okay. If you decide to change to sand, I have read that regular play sand you can get at Lowe's or any home improvement store is fine and it's very inexpensive.0morrokh said:Also, I need some tips on substrate, since I know Cories like to dig. Can you buy very fine gravel at fish stores, or should I use sand? If so, where can I buy fish-safe sand, and in small amounts? Risht now I just have very coarse gravel, but I'm afraid it will hurt the Cories' little whisker thingys.
