Temperature
Maintaining a stable and appropriate temperature is critical for the survival of aquatic life.
pH 7.8 - 8.4 potential of HydrogenMeasuring the acidity or alkalinity of water on a 0–14 scale, where 7 is neutral, 7 is alkaline.
NO3 1-20 ppm NitrateWhile less toxic than ammonia, high nitrate levels (above 40–80 ppm) are important to monitor because they can cause fish stress, stunted growth, and harmful algae blooms.
NO2 <0.0001 ppm NitriteIt is a highly toxic, intermediate compound in the nitrogen cycle produced from broken-down ammonia
PO4 0.01 - 0.1 ppm PhosphateIt is essential for plant development but must be managed, as excess levels trigger nuisance algae blooms and inhibit coral calcification.
NH3 <0.1 ppm AmmoniaIt is the primary killer of aquarium fish, causing gill damage, stress, and death
Ca 380 - 450 ppm CalciumSupporting the growth, skeletal structure, and shell formation of corals, mollusks, crustaceans, and coralline algae
KH 8 - 12 dKH AlkalinityIt acts as a shield, neutralizing acids to prevent dangerous pH "crashes" that can harm fish, corals, and plants.
Mg 1200 - 1400 ppm MagnesiumIt enables coral growth by supporting skeletal formation, assists in metabolic processes, and ensures that calcium is available for corals, clams, and coralline algae.
SG 1.023 - 1.026 SG SalinityEssential for maintaining stable, natural water parameters, proper osmoregulation, and stress-free environments for marine fish and corals
ORP 250 - 400 mV Oxidation-Reduction PotentialA higher positive mV indicates clean, oxygen-rich water with high water quality, while low readings indicate high pollution.
About Trapezia Pocillopora Crab
General information
The Trapezia Pocillopora or Acropora Crab is well known for its symbiotic relationship with acropora corals. The crab helps the coral in keeping its branches clean and allowing proper water flow. It feeds on food matter that can be found on the corals. It also guards the coral againts predators and invaders. Higher survival rates and growth rates have been noted in this species. Therefore, it is a good addition to the aquarium. It is of different colors and it can grow up to 1 in.
Diet & nutrition
It is a carnivore mainly subsisting on coral polyps, detritus, and the mucus secreted by corals.
Origination
It is native to Indonesia and Maldives.
Cautions
Like most invertebrates, the Acropora Carb does not do well if there are large swings in water parameters. They also do not tolerate any types of metal traces in the water, therefore you should never be in contact with any copper medications.
Acclimation process
Most invertebrates don't like large swings in water parameters and the Acropora Crab is not an exception, so even though most hobbyists do not acclimate their cleaner crews it is suggested to do so. If you have a sump, float your cleaner crew in an area with low light to allow them to temperature acclimate first which should take about 15-20 min. Then it is best to slowly drip acclimate them to allow them to adjust to your water conditions.
