:;fr Hello, my husband (Mike) and I (Dawn) just started a 15 gallon tank about a month ago. We have a 4 year old daughter who is loving it! It was a rough start at first! we lost some fish. But now i think we are ok. I THINK!! We have tetras, plattys and suckers as well as decorations. We are learning as we go. So any advice will be greatly taken!
