Elysia Clarki Diet: Bryopsis, Penicillus, Halimeda

Elysia crispata Diet: Halimeda, Penicillus






Please Note:  Any new fish purchased from us or from a local pet store should to be quarantined.  All fish from anywhere in the wild can be possible carriers of bacteria and protozoa that can lead to an infection in your system, so we always recommend that you use some sort of quarantine system prior to adding them to your system.  If you have a fish only system and can medicate the whole system, you may not need a separate quarantine tank.  If you have a reef system that cannot be medicated, a good ultraviolet sterilization system should prevent any kind of disease outbreak.  We medicate our system for bacterial infections and protozoans, but because we don’’t always hold our fish for long periods of time, there is no way to be sure all the protozoan cysts have been killed.  A little bit of prevention will save you lots of trouble down the line.

    Excellent guys for bryopsis control if you don’t want to or fail with chemical methods. Ordered a couple of times and always get the right species, and healthy – the only reason I needed to reorder was when they detach and go for a swim they occasionally land on one of my large fungias and get eaten.

    This is the second time I ordered this lettuce sea slug. The first time I ordered two and one was yellow like the picture and the other was yellow white with neon green.

    This time I received a really healthy frilly white one. Im sitting about 10 feet from my tank and I can see this guy cleaning away!

    Again I have to praise the quality of sea life Kara and Philipp send to their customers. I have bought some of these at local stores in the past and none were as lively and healthy as the ones from KPaquatic.

    This is another little guy that I would just add to my cart if I am ever ordering from them. Always on the move cleaning my glass, better than the snails! If you have never had one of them before they are quite entertaining when they decide to detach the float around and look like ballerinas until they get to their next feeding destination.

    I have been keeping Elysia clarki, the common lettuce slug of the keys for some time now. I received a small group of them from KP Aquatics a few months ago, and they have been feeding, laying eggs and generally thriving. After I recieved the clarki, I mentioned to Kara that I was interested in E. crispata as well. I forgot about it, then received an email from Philipp that they had collected some crispata, so I jumped on the opportunity. The crispata were absolutely gorgeous, and have done very well in their new home.
    I would definitely recommend the slugs of either species to anyone who has a good growth of green macroalgae or hair algae in a low-flow tank.

    They are awesome little fellas! I had one for a very long time, cleans algae very well and are very interesting to look at. Just cover your pump intakes as I lost mine because it got sucked into a powerhead!

    Very good cleaners, will eat bryopsis hair type algae. Not many other critters eat this stuff, so this is a great critter to have, strictly herbivores. Also very pretty to look at.

    The picture does not do this justice. The green color and wild frilly edges are most entertaining to watch.
