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 Tiger Tail Sea Cucumber

General information

The Tiger Tail Sea with its brown body spotted with white and dressed in numerous spiny papillae, Holothuria sp. is also a visually stunning addition to the home aquarium. Since it is a very adept and agile scavenger, the Tiger Tail Sea Cucumber can clean detritus from beneath rockwork and difficult-to-clean tight corners. Native to the oceans of the Indo-Pacific, this member of the Holothuriidae family can grow to impressive lengths of up to six feet long in the wild. In the home aquarium, however, most max out in length between 12" and 18" long. In general, keep only 3 inches of worm for every 20 gallons of aquarium water. For best care, the Tiger Tail Sea Cucumber should be kept in larger systems with thick sand beds and rocky caves for shelter. Interestingly, the Tiger Tail Sea Cucumber is one of the few species that attaches its lower body to the inside of its shelter and only extends its anterior half when searching for food. Like other Sea Cucumbers, Holothuria sp. has the potential to poison an aquarium. The Sea Cucumber cannot tolerate high nitrate levels or copper-based medications.
