Care
Care notes
Temperature 22–28 °C, pH 8.1–8.4, salinity 1.020–1.025. A minimum 100-liter tank is recommended, preferably tall (60 cm) for vertical swimming. Water flow should be low to moderate. Diet should consist of enriched mysis and brine shrimp, fed several times a day. Avoid fast or aggressive fish. Seahorses are sensitive to diseases and water quality. A protein skimmer is useful. Keep nitrates below 10 mg/L and phosphates below 0.05 mg/L. Decor with gorgonians or algae allows for anchoring.
