Well hi, thestever, and welcome to the AA forum.
I think maybe the reason that you haven't gotten any replies as yet, is that the members are stunned. Have you ever researched what your pets need? And how long have you had this stocking situation. What kind of filtration are you using, and what is a child fish tank???
Here's the thing: any where you research this, I think you will find that for goldfish, you need a 20 gallon tank for the first one, and 10 gallons larger for every goldfish after the first. And I'm not sure, but I think that the same guideline applies to mollies, as well. That would mean for the goldfish, you'd need a 150 gallon tank, with really good filtration, and lots of partial water changes. Is this really something you want to commit to? Because I'm afraid that you will begin to see your pets suffer, unless you are doing water changes a couple times a day.
Do you check your water parameters? Like ammonia, nitrite and nitrate? If so, how are you doing with them? What type of filters do you have running on your tanks? We would need more of this type of information to help you with your stocking issues.
I hope you are not offended by these questions, because I'm not trying to be confrontational in any way. We have, most of us anyway, all made many mistakes on our way to becoming aquarium hobbyists, some small mistakes, and some large. So you are not alone, and we truely want to help you understand how to take care of your pets. There are some articles for beginning hobbyists that you might be interested in and here is the link:http://www.aquariumadvice.com/forums...es-154837.html
I wish you the best of luck, and feel free to ask any questions, and we will attempt to help.
