Water parameters

Temp 76-80 F Temperature

Maintaining a stable and appropriate temperature is critical for the survival of aquatic life.

pH 7.8 - 8.4 potential of Hydrogen

Measuring the acidity or alkalinity of water on a 0–14 scale, where 7 is neutral, 7 is alkaline.

NO3 1-20 ppm Nitrate

While 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 Nitrite

It is a highly toxic, intermediate compound in the nitrogen cycle produced from broken-down ammonia

PO4 0.01 - 0.1 ppm Phosphate

It is essential for plant development but must be managed, as excess levels trigger nuisance algae blooms and inhibit coral calcification.

NH3 <0.1 ppm Ammonia

It is the primary killer of aquarium fish, causing gill damage, stress, and death

Ca 380 - 450 ppm Calcium

Supporting the growth, skeletal structure, and shell formation of corals, mollusks, crustaceans, and coralline algae

KH 8 - 12 dKH Alkalinity

It acts as a shield, neutralizing acids to prevent dangerous pH "crashes" that can harm fish, corals, and plants.

Mg 1200 - 1400 ppm Magnesium

It 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 Salinity

Essential for maintaining stable, natural water parameters, proper osmoregulation, and stress-free environments for marine fish and corals

ORP 250 - 400 mV Oxidation-Reduction Potential

A higher positive mV indicates clean, oxygen-rich water with high water quality, while low readings indicate high pollution.

About Strawberry Crab

General information

The Strawberry Crab or Red Boxing Crab is bright pink in color with numerous white spots. Their claws are blunt and flat that are made for picking up algae. They can grow up to about 5 cm (2 in) wide. They interact harmoniously with other invertebrates in the aquarium and so they are reef safe. 

Diet & nutrition

It is an omnivore that helps in preventing algal bloom in the aquarium. Aside from algae, it can also feed on uneaten food. It is part of the so-called "cleaning crew". In cases of food scarcity, it can be fed with herbivorous and meaty food.

Origination

It originated from the waters of Hawaii.

Cautions

Like most invertebrates, the Strawberry Crab does not do well if there are large swings in water parameters. It also does not tolerate any type of metal traces in the water, therefore, it should never be in contact with any copper medications.

Acclimation process

Most invertebrates do not like large swings in water parameters and the Strawberry 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.
