I don't think you're ready for this jelly

Last time we were talking about my glass jellyfish, this ended up taking us onto the topic of my love for the little creatures and how I also had them as pets.

I mentioned how @Stormriderstudio had bought me them as a Christmas gift. There is a little back story there.

It all started in November, I was told we were going out for the day.
I had to drive to an undisclosed location, interesting considering sometimes me and him don't always agree on his navigation.
I was told that the place we were going to would give me a clue about my Christmas present, it took just over an hour to get where we were going but we eventually arrived at The Deep in Hull (an amazing aquarium for all types of marine life.)

While we looked at and thoroughly enjoyed everything there (the was even a glass sculpture installation of a coral reef, though it was too dark in that room for any photos of it.) But once we got to the jellyfish room I was told what I would be getting for Christmas. I spent as long as I could looking at all the jellyfish there. This is where I truly fell in love with the pacific sea nettles, they were so beautiful.

But onto the actual present. One of the reasons for telling me early was because the tank had to be set up and running for a little while before you could introduce the jellyfish to their home. We decided to order the tank so that was here for me to open Christmas day and I would get the jellyfish when I felt the tank was ready.

The tanks for jellyfish have a special design, jellyfish can not swim without a current so the tank needs to be a kreisel tank so it circulates the water to mimic a current. The tank also has to be smooth so there is nothing the jellyfish can get caught on and damage their bells.

The tank I got has an inner and outer ring. The pump, substrates and all the pipes sit in the outer ring the jellyfish live in the inner ring slowly floating round in the circle. I have 2 Moon jellyfish, they are a common breed and don't have a sting, which is a good thing as mine like to hug my hand if I put it in the tank to clean inside the inner ring.

Jellyfish are kept in saltwater, so the first thing I had to get to grips with was maintaining water quality. I was mixing the salt water myself as the optimum PPT (parts per thousand) of salt to water for these jellyfish was 33 not 35 which is used in most other saltwater tanks.

Feeding them is quite simple, you can go quite in depth and breed and hatch your own baby brine shrimp, although there are "instant" varieties of food. I use a powder that I mix with a small amount of the water from the tank before feeding them. The food shows up in the water as orange flecks and you can see the jellyfish pick up the food and when it is in their stomachs (so you always know when they are full) They are fed once a day but unlike most other pets jellyfish shrink when they don't eat, so providing they are a decent size and healthy you can go on holiday and not have to worry about feeding them.
