Hi Everyone!
Well, it's my girlfriends birthday coming up and she loves jellyfish. I don't mean that in a "I love pizza it's great" kind of way either - she seriously loves jellyfish. Sometimes I think it's a little disturbing, and then I realize that I am way worse when it comes to corals etc.
So, why not build her a jelly pseudokreisel (PK)! For those who are unfamiliar with PKs, they are specifically designed tanks that allow for circular water movement with no corners. Jellies suck at swimming and will get stuck in a regular aquarium -- that's why when you go to a public aquarium you see all these fancy tanks with the jellies.
For interest sake, a "kreisel" has water being pushed down from the top center as part of the return and upwards via closed loops along the side to create two circular flow patterns on either side of the tank.
Here is an example from the monteray bay aquarium.
A "pseudokreisel" also does a circular current -- but rather than two on either side there is just one circular current.
I can easily obtain moon jellies ephyra (baby jellyfish) but they would eventually outgrow my planned aquarium. Moon jellies:
But what I really want are some sea gooseberries or "ctenophores"
The ctenophores are her favorite type of jelly, and mine as well. I think they would also do much better on the size of my planned PK.
In my subsequent posts I'm going to show you what I plan, and we will go from there! I'm excited
