Hello all this is a few pictures of my jellyfish I have been takin care of for almost 2 years now. Enjoy.
Those are pictures at feeding time. The jellyfish are fed live baby brine shrimp every other day as well as rotifers for an even diet. There is a layer of mucus on the bell that initially traps the shrimp. As the jellyfish pulse the tentacles which are fine hairlike structures around the perimeter sting and kill the brine shrimps which are collected in large clumps.
Within minutes the oral arms which are the long ribbon like structures reach out to the clumps and begin to wrap around the food particles which travel to the stomach very slowly INSIDE of the oral arms. The stomach are the horseshoe shaped structures in the bell. They 'suck on the food for a while. Removing nutrients. Then they spit it back out. Which is then waste.
After they eat they change color to the food that they just consumed. In this case they take on an orange pearlescent color. Pretty cool to see. Hard to photograph. Its almost like a ghostly orange.
My tank is chilled and filtered over twice before being returned to the display area.cold water is critical to the animals health. 70 degree water is the sweet spot it seems. I maintain salinity constantly 1.024 sg.
This value must be maintained within .001 unit otherwise they will experience osmotic shock and get really messed up! They acutally will ball up in utter refusal of the water conditions if you let it get out of hand. This happened to me only once.
I hope you guys like it!
Edit. Here is a zoomed out picture of the whole tank. And a general picture of all of them swimming around.
This is a picture after feeding time. These jellies are full! I rarely allow them to eat THAT much food though. Reason being increased nitrates obviously from the waste and I cant have them get too large.
Jellyfish adapt to amounts of food RAPIDLY and grow alarmingly fast if allowed to gorge theirselves.
If I fed all of them that much food for one week they would probably add 1/2 an inch to their bell. They shrink and grow proportional to intake. That is why they are so hardy in the ocean. When food is scarce they shring to smaller than a penny so that they have less caloric needs and can skate by on less food.
