Yep, the name is a bit of a mouthful, but the “magnifica” part is quite appropriate. This little guy is a sea slug, a member of the nudibranch species, and he joined my fish tank on Friday. This Chromodoris Magnifica is about 2 inches long, with bright vibrant colors, and with bright orange gills and rhinophores. He’s (ok, we don’t know that he’s a he, but “it” seems so impersonal) also surprisingly agile, and can slither around, but also just kind of lets go and allows the current drop him down somewhere else.

  1. Very cool looking. I thought most nudibranchs eat one thing and one things only (species dependent). What does this one eat? Beautiful…good luck with it!!
    Do you keep corals as well?

  2. Where are these sea slugs? Tropical waters? What water depth? Are they exotic or can you find them at any pet store to put in your fish tank? Thanks for posting this…something I’d like to add to my fish tank.

  3. I try to keep my pH level at 8.2, +/- 2 in each direction (it is 8.3 right now). I use a digital controller to monitor pH (and more), it alerts me to changes in real-time.
