The jellys are about £35 each and the tank cost about £250 (did I mention how awesome @stormriderstudio was for such a wonderful Christmas present?)
Here's the tank on the manufacturers website; http://www.cubicaquarium.com/orbit-20/
The hardest part is getting the water quality right. This is turning into a post in it's own right...
it really is.... hahahahaha save all these comments and just put them into a post! Easy! :)
and my hubby will karate chop me if i want a tank like that hahahahahaha
so.... i guess i shall wait until i am a steemit dolphin and THEN i will get myself a jellyfish tank hehehehehehe
The good news is after the tank they are really cheap £8 for a pack of food that lasts MONTHS.
You could always try the tact of it being a lot cheaper than having a dog for a year.
