    Sure is easy to spot. Have you had good luck with them?

    I think nudibranchs only fluoresce if they've eaten something that fluoresces. Anything else they could have eaten?

    @Zinovate:
    I bought two really small ones and released them into a tank filled with aiptasia and never saw them again. I then heard that shrimp love to eat them -- especially peppermint shrimp and I had about six of those in the tank at the time (and none of them eating the aiptasia) so I figured the shrimp ate them. So my choices were to trap the shrimp and quarantine them while the Berghia did their job or do it the following way.

    I bought four more and put these into a separate 10-gallon tank and put rocks with aiptasia on them into the tank for them to feast on. Once you see them high up on the glass you know the rock is clean and they're hungry again. As of right now I have a few aiptasia in their 10-gallon tank and zero in my 75 gallon. the Berghia are an inch long now and voracious predators leaving absolutely nothing behind of the aiptasia (unlike most other predators). Since I'm running out of food, I'm selling them. See the following listing:

    @NightStar:
    Berghia's diet is exclusive to aiptasia -- without aiptasia, they die of starvation. With regard to their fluorescence, take a look at the bottom of the following page for a discussion on this as it would appear this is captured from eating aiptasia:
    https://saltyunderground.com/categor...ptasia-control

    Here's the beginning of the relevant part:
    "Berghia also have been shown to harbor the Zooxanthellae, the photosynthetic symbiotic algae found in corals. While utilizing a very primitive form of symbiosis, the Berghia is able to capture zooxanthellae from the Aiptasia. Research has shown that these symbionts continue to perform high levels of photosynthesis and remain in the Berghia’s cerata for as much as 6 days before being excreted."

    Enjoy!

    Too bad they didn't start reproducing in your 10 G. One hell of a DBTC
