Choosing the right saltwater fish for your tank

Tank size comes first. Small gobies, blennies, and clownfish are comfortable in 20 to 30 gallon systems, while tangs, larger angelfish, and triggerfish need 75 gallons or more with plenty of swimming room. Most marine fish do best at 75 to 80°F, a specific gravity around 1.023 to 1.026, and a pH near 8.1 to 8.4.

Decide whether your tank is a reef or a fish-only setup. Reef-safe species such as clownfish, most gobies, and many wrasses leave corals alone, while butterflyfish, larger angelfish, and triggerfish may nip at coral and invertebrates. Feed marine flakes or pellets, frozen mysis and brine shrimp, and nori for herbivores like tangs, and add new fish slowly.
