A Jellyfish "Combo" Tank

At the Monterey Bay Aquarium they held jellyfish in large holding tanks. Sometimes they get creative and try different types of jellyfish together that are from the same place as shown here:

I just love the idea of having a tank with more than one jellyfish. So I decided to take on this challenge for myself.

This is the tank. It is a 20 gallon tank with my first 5 upside down jellies and my cleaner snail. I'm enjoying the tank so far. It is really big and the jellies love it. I'm also getting 10 more upside down jellies in the mail in the next day or so. At the same day I will pick up more cleaner snails. Then I will work on getting lagoon jellies and blubber jellyfish. I've never kept either of these types before. Lagoon jellies are positive to get along with upside down jellies, but the variable here is the blubber jellyfish. Blubber jellies and lagoon jellies will get along together so I am hoping upside downs will get along too. Like Thomas Knowles says, have fun and be creative! If this does not work out, I'll get rid of the blubbers and keep just the two types of jellies left. Although I am nearly positive they will all get along with each other.

Major Moon Tank Crash

So my moons were doing very good, and swimming good. Two days later, they looked like they were getting eaten alive. The ammonia had rapidly climbed to 7ppm, very deadly reading for any fish or jellyfish. I quickly moved them to my coldwater tank. However, I was too late for one of my favorite warm waters Yoshi, he was alive but not pulsing ever. The other warm water was inverting the other day, but it back to normal. Trio, my 3 circled jelly, has lost his oral arms due to the spike in bad water. It looks like he is growing them back, but I would not be sure. Yoshi was let go this weekend into the ocean. I hope he will continue his life there and recover.

I have other news as well. My upside down jelly newborns were gone when I woke up the other day. I new it is pretty impossible to do it right on the first time. I tried my best, but sadly it did not work out too well.

More happy news now...
I am almost done building my huge 20 gallon tropical combo tank. Just needs water.
Also, I have tons of these new type of jellyfish. They invaded into my system somehow. They are making more, now I have about 20. I'm selling them on Thinkjellyfish.com now for 5 dollars. They get along with my upside downs.
