Alveopora tizardi Bassett-Smith, 1890
Description Alveopora tizardi: Colony: flat or wavy plates. Corallites: septum spines usually regularly tapered. Polyps: short with button-like tentacle tips. Color: pale pinkish brown to bright pink, occasionally with gray mouth discs and white tentacle tips
The Harazaki coral shrimp Pliopontonia harazakii, which was only described in 2009, lives as a commensal on Alveopora tizardi.
In 2023, colonies of Alveopora tizardi were found as epibionts on mollusc shells in an anchialine lake of a raised atoll, Kakaban Island, East Kalimantan, Indonesia.
The conditions for Alveopora tizardi in this closed, sea-independent lake are extreme: the water temperature, salinity and pH at the cave site were 32 °C, 24 psu and 7.4, respectively. Science has not yet been able to clarify whether Alveopora tizardi survives there permanently and comments “An opportunist or a survivalist?”.
Similar species: Alveopora japonica. See also Alveopora spongiosa, which has larger corallites and prominent polyps.
General:
Daisy corals, such as Alveopora and Goniopora, have been very popular in aquarium maintenance for many years.
The main difference between the two species:
Alveopora polyps have 12 tentacles, while Goniopora polyps have 24 tentacles.
Some of them are easy to keep and can then often be easily propagated. Certainly not all species are the same, and some are still considered difficult today. Nevertheless, with the many additives that we have today and the appropriate feeding, it is easier than it used to be.
We know that many cover part of their diet with the light, but the species that can also filter usable material from the water are the ones that are really fit and characterized by growth. We have found that the species to which dust food (planktonic) is added grow better and are in better condition.
Gonioporas and Alveoporas should receive a moving but never direct current. Otherwise they will not open up. They require a medium light intensity and can therefore be established between the center and bottom. They are not quite as sensitive to water quality, but you should still offer them low concentrations of No3 and Po4 in the water.
Experience has shown that they do better with trace element supplements and more frequent water changes, which also indicates that they can absorb a lot of other things from the water in addition to food.
Determining the species is not that easy, despite good reference books. To be able to do that 100%, you would need to have a skeleton.
Therefore, we also have to classify species as sp. from time to time.
Similar species: Alveopora japonica. See also A. spongiosa, which has larger corallites and distinctive polyps.
