So I have always wanted to have my own aquarium ever since I was little and now that I have gotten to the point where I am able to properly raise fish, I am really into it. So I got 2 red eared sliders for my birthday and I have had them for about 4 months now! So I am not completely new to this. I just recently got some Mollies from my LFS and I currently have 5 of them [2 black, 2 orange, one white and black (3 female and 2 male I believe)] in a 10 gallon aquarium. Now I know this might be a little on the smaller side but I am looking to get a 30 gallon in about a month or so after I move. (If they do need to be in a bigger tank before than, please let me know and I can get a bigger one) I am just basically here asking for some advice. Now I have noticed that they have been staying near the top of the water for quite a while, although they have been doing it less, I read that this could be to an Ammonia problem. I really didn't know about Cycling my tank before I did any research. They have been in the tank for about a week now, are they going to be fine? Also I have been back and forth on keeping some gravel in my tank. Right now I don't have any in it because I just think it is so much easier to keep clean. Should I use gravel or not? Oh and I currently don't have the water salted but I have been reading that the Mollies do better with salt. So should I add salt? Basically I just want to get really educated on this and I believe these forums (if they are active) will be my new home! Any help is greatly appreciated! Sorry if this is all scattered.
