PE Mysis
Top PickThis frozen mysis is one of the most trusted high-protein foods for marine fish and is often accepted by difficult eaters. It is especially useful during quarantine, acclimation, and conditioning broodstock.
Pros
- +Large, protein-rich mysis often triggers strong feeding responses
- +Excellent for finicky carnivores and recently imported fish
- +Useful for target feeding larger LPS corals and some invertebrates
Cons
- -Requires thawing and more hands-on feeding
- -Can raise nutrients quickly if overfed or not rinsed
LRS Reef Frenzy
A premium frozen blend designed for reef tanks, combining seafood ingredients with particles suitable for both fish and many corals. It is one of the best all-in-one options for mixed reefs with varied feeding needs.
Pros
- +Broad particle size range feeds fish, shrimp, and many filter-feeding reef organisms
- +Highly palatable blend helps transition stubborn fish onto prepared foods
- +Convenient choice for hobbyists feeding both fish and corals in one session
Cons
- -Premium price compared with basic frozen foods
- -Can contribute to phosphate and nitrate if broadcast too heavily
New Life Spectrum Marine Fish Formula Pellets
A widely used staple pellet for marine fish that offers balanced nutrition and consistent sizing. It works especially well for community reef and FOWLR tanks where convenience and clean feeding matter.
Pros
- +Sinking pellet format suits many clownfish, wrasses, tangs, and angelfish
- +Produces relatively low waste when portions are controlled
- +Easy to use in repeatable daily feeding schedules
Cons
- -Some newly imported fish refuse dry foods at first
- -Less attractive than frozen foods for finicky feeders like mandarins or picky butterflyfish
Two Little Fishies SeaVeggies Seaweed Sheets
Seaweed sheets are an essential feeding option for many herbivorous marine fish and a valuable enrichment tool. They are simple, effective, and often necessary for reducing aggression in tang-heavy systems.
Pros
- +Excellent for tangs, foxfaces, and some angelfish that graze all day
- +Helps reduce pacing and aggression by encouraging natural feeding behavior
- +Easy to clip in multiple areas to spread out dominant fish
Cons
- -Needs a clip or feeding station and regular removal of uneaten pieces
- -Not a complete diet on its own for most fish
Reef Nutrition TDO Chroma Boost
A premium small pellet originally popular in breeding and grow-out systems, with strong acceptance from many marine fish. Its fine size options make it especially useful for juvenile fish and smaller species.
Pros
- +Available in very small sizes for juveniles, gobies, and captive-bred fish
- +Excellent choice for consistent portioning in breeding or grow-out systems
- +Often accepted faster than larger standard marine pellets
Cons
- -Higher cost than many general-use pellets
- -Not ideal as the only food for larger herbivores or specialized grazers
Ocean Nutrition Formula Two Marine Pellets or Flakes
A classic herbivore-leaning prepared food that supports tangs, rabbitfish, and omnivorous community fish. It is a practical option for tanks where algae-based nutrition needs more emphasis.
Pros
- +Includes vegetable matter that supports herbivores and omnivores
- +Available in flake and pellet formats for different feeding styles
- +Works well as part of a varied daily rotation
Cons
- -Not as enticing as frozen food for shy or newly imported fish
- -Flakes can break apart and spread through overflows easily
The Verdict
For most saltwater fish keepers, a pellet staple like New Life Spectrum or TDO Chroma Boost paired with a frozen food such as PE Mysis gives the best balance of convenience, nutrition, and feeding response. Mixed reef hobbyists often get the most versatility from LRS Reef Frenzy, while tang and rabbitfish owners should keep seaweed sheets in regular rotation. If you are working with quarantined, stressed, or finicky fish, frozen mysis is usually the safest first choice.
Pro Tips
- *Match food particle size to the fish's mouth size and feeding style, especially for gobies, wrasses, and juveniles.
- *Use at least two food types in rotation, such as pellets plus frozen, to cover herbivore and carnivore needs more completely.
- *For reef tanks, feed only what fish consume within 30-60 seconds per pass to limit nitrate and phosphate spikes.
- *If a fish is newly imported or in quarantine, start with highly palatable frozen foods before trying to transition to pellets or flakes.
- *Herbivores like tangs and rabbitfish do best when seaweed is offered several times per week, or daily in heavily stocked systems.
