species of Gracilaria are highly variable depending on the
environment collected, which can make proper identification
difficult. Tikvahiae features green, brown and red coloration
with long, slender, cylindrical branches attached by a single
holdfast. In turbulent environments it grows more compact and the branches can be somewhat flattened. Most all varieties are
found in moderate to shallow water, attached to hard bottom and
rock outcroppings. Species of Tikvahiae are also found as free
floating specimens, lacking any holdfast, composed of a large
circular clump. This particular red algae does very well in the
marine aquarium or refugium and is a great food source for fish.
Its growth is slow to moderate depending on the availability of
light and nutrients. Most species of Gracilaria do well with
moderate current and brightly lit aquariums. In the refugium, it
most commonly allowed to tumble continuously with moderate to high
flow. Very palatable to tangs and angels as well as other herbivores.
