Query: Sea Monkeys Are Over Rated

We were very disappointed with this kit. We followed the instructions exactly. We used purified water, temp control, lighting, aerating the water, feeding etc. When the sea monkeys "hatched", we could barely see them. But after a few days they got bigger and we were getting excited. We had about 30 of them. Then by day seven, all but two of them died! If you are going to buy this, get the air pump ahead of time. Maybe that will help. The light also burns out quickly because it is battery operated. They make these creatures out to be like little people. The fact is, they are very small, fragile and much more care taking is involved than expected. I would gladly do it if the little creatures would live long enough to get some enjoyment. The guarantee is also only for replacement, which requires you to send them a shipping fee! I don't want to bother with it.
