Comments about Big Time Toys Sea-Monkeys - Magic Castle:

I agree with another review that the information was a little manual said to feed after five days, once said after the eggs hatched. The one said to feed every other day, one said to feed when the food was low and to ensure that the water was not cloudy. Otherwise, very very easy to use, easy to maintain, and interesting to watch. I love having this fabulous pet that requires such little time to care for!

Comments about Big Time Toys Sea-Monkeys - Magic Castle:

The product didn't explain very well of how to maintain these "brine shrimp". Like for example, on the food packet it says to feed them every other day after they hatch, which actually lead to a fungus growth in my girlfriend's tank because of all the uneaten food. Unless you have 100 adult sea monkeys in your tank, you shouldn't be feeding them every other day. Anyway, because of this fungus, many of my girlfriend's sea monkeys died and she was devastated. Basically nothing is explained thoroughly with this product.

The manual is smaller than the product booklet that's trying to sell you stuff. It's just a company trying to make money off of you. Even on the main website it talks about how sea monkeys are very different than brine shrimp, when in reality they're the same thing, the only diffence is that they were just bred to be more superior than the average brine shrimp. They're raised the same way and I have proof of this because I moved them into a larger tank and they're perfectly fine. So I highly doubt that there isn't another less expensive alternative for sea monkey food.

In addition, the castle made it very difficult to use the aqua-leash for cleaning up and moving sea monkeys around. Not only that, but the castle just blocks your view and it doesn't help that the container is circular. Watching the sea monkeys run into the castle wasn't all that appealing either. I actually felt sorry for them, especially when they got stuck in the corners of the castle. I recommend getting sea monkeys, but not in this awful container. Also it would be nice to have an up-to-date guide, especially on the official website.

        i love this! I have had them for a few months already. i placed it right next to my window and they looove it, i just noticed there are 100+ babies in my tank! more and more eggs are hatching, my 6 originals are very big and they laid more eggs which is why there are so many teeny tiny babies!! cool gift to give, worth my money! the thing not to great is that i cant really change the water, i dont want to kill any babies, and you only can use filtered water. but still GREAT
