Aiptasia is a genus of a symbiotic cnidarian belonging to the class Anthozoa (sea anemones, corals). Aiptasia is a widely distributed genus of temperate and tropical sea anemones of benthic lifestyle typically found living on mangrove roots and hard substrates.

These anemones, as well as many other cnidarian species, often contain symbiotic dinoflagellate unicellular algae of the Class: Anthozoa. In this study, transmission electron microscopy was used to conduct a detailed examination of symbiotic tissues of the tropical anemone Aiptasia pallida during early stages of host stress.

Nevertheless, the cellular and molecular processes by which elevated temperatures elicit the bleaching response are poorly understood. This dissertation deals with this important question by describing two mediators of cnidarian bleaching in the model symbiotic tropical sea anemone Stress induced changes in optical spectra and pigmentation of the sea anemone Aiptasia pallida book pallida (Verril), namely nitric oxide and by: 6.

We worked with the symbiotic tropical sea anemone, recently renamed Exaiptasia (Aiptasia) pallida.

Corals exposed to environmental stresses need to engage appropriate physiological strategies to survive. Here, we examined tissue modifications following algal dysfunction. Aiptasia pallida was exposed during 1 week to 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU), the herbicide called diuron.

Voolstraa,2 aRed Sea Research. The idea behind Aiptasia- X is that the active ingredients are suspended in some kind of “Micella” which is like a liquid capsule and only after ingested by the anemone it becomes free.

Although I understand that this is the only change you made in the tank, I don’t think that there is a straight connection to the illness of the fish. The small sea anemone Aiptasia provides a tractable laboratory model for investigating these mechanisms.
