  1. My crab loves it! 4 Star Rating

    Tristan on

    We had a problem with our crab climbing the airtubes to hang out at the top of our tank above the water. Now, she won't leave the Underwater Lagoon! She loves it! With the feeder - it's super easy to get her food. Putting it into an already setup tank was a slight hassle, but overall, we're very satisfied (and so is the crab!). Very good value, though the plastic was a little scuffed up. Cleaned up fine.

  2. Escape no more 4 Star Rating

    Unknown on

    Crab loves it. He quit trying to escape after i put this in my tank. It was a pain to install since I had to break down my tank, but it was well with it.

  3. Nice alternative 4 Star Rating

    Ashley on

    I got this biosphere to enable my fiddler crab to be able to breath under water. He doesn't go in it as much as I would like but it does help because I don't have to take him out of the tank for him to dry and get air. Perhaps if I fed him live food in the biosphere he would go in it more often.

  4. Underwater Lagoon is hit with crabs, not literally! 4 Star Rating

    Phil on

    Overall I'm very pleased with this product. Takes a while to set with no water marks on inside of glass but worth persevering with for best view. I lowered it in gently and level with inside of glass dry. Beware air bubbles spitting water! I have the air pipe slightly above ground level but you don't notice it unless really looking! There's probably a better way to avoid air bubbles inside the glass, ask the sales team, great service. Once set up in the right place with clean clear glass it's pretty cool. Crabs found it within a few hours and are in and out a lot. Glass had a few marks and scuffs which initially worried me as I thought it would affect the view but once in the water it's ok. Good value and great to see the crabs using it!

    Very easy setup. I'm amazed at how it works! Took 2 days, but Crabby the Crab found his new home and seems much happier. He hasn't tried to escape the tank for days now. Thanks!!

  7. Great bio dome :) "lagoon" 5 Star Rating

    Jason S on

    I have a 20H gallon aquarium with Australian rainbow fish and a spotted puffer fish that bumps into the clear cover (force field) works as promised I also bought the feeder tube and it works well now all it needs is a remote control under water switch light for night viewing. :)

  8. Perfect for the 10 gallon tank 5 Star Rating

    Alison Simard, mother of 2 children, 5 fish and one very happy male fiddler crab. on

    I was desperate to find a solution when I learned that my fiddler crab in my tropical fish tank wasn't meant to be underwater all the time. No wonder he kept escaping into our filter. So thrilled when I found this product. The customer service was way beyond my expectations both in selecting the right habitat for our tank and fish and crab to set up and feeding. The whole family is regularly transfixed at the tank watching our fiddler crab in his habitat and watching the benefits the other fish find in the shallow water underneath. Can't recommend a better product and better customer service. Its too bad more fiddler crab sites and fish stores don't carry this product. I can't imagine it will stay a secret for long.
