Aquarium fish treats
Fish treats are freeze-dried or dried live foods like bloodworm, daphnia and tubifex, fed alongside a normal staple diet rather than replacing it, and most fish take to them quickly once they are used to them. We stock several of these for variety, whether your fish are tropical, coldwater or marine.

What counts as a fish treat
King British Bloodworm Treats and Tetra Delica Bloodworm are both dried or freeze-dried bloodworm, high in protein and fed as an occasional addition to a diet of staple flake or pellet food. King British Daphnia Treats and Supa Daphnia cover the same idea with daphnia instead, and King British Tubifex Fish Treat is suitable for fish as well as turtles and terrapins, so it crosses over between the fish and reptile side of the aquarium aisle.
Freeze-drying and drying are both used to preserve these without needing to keep live or frozen cultures, which is more practical for most home aquariums, and Tetra Delica Bloodworm comes in mess-free sachets specifically to make dosing easier than handling loose dried food.
How much and how often
Treats are meant to be occasional rather than a daily staple — a diet built mostly around bloodworm or daphnia rather than a complete flake or pellet food is missing nutrients those staples are formulated to provide. A small pinch a couple of times a week alongside normal feeding is a reasonable way to use most of these.
Overfeeding any treat, dried or otherwise, is one of the more common causes of poor water quality in a home aquarium, since uneaten food breaks down and affects the water rather than simply disappearing, so little and often beats one large feed.

Common questions
- Can I feed my fish bloodworm every day?
- It is better used as an occasional treat alongside a complete flake or pellet staple rather than a daily food, since a diet built mostly around bloodworm or daphnia will miss nutrients a proper staple diet is formulated to provide.
- Are fish treats suitable for turtles too?
- Some are — King British Tubifex Fish Treat is suitable for fish as well as turtles and terrapins, so it is worth checking the specific product if you are feeding a mixed aquatic set-up rather than fish alone.
- How much treat food should I give my fish?
- A small amount a couple of times a week alongside normal feeding is generally enough — overfeeding any treat food is a common cause of poor water quality, since anything uneaten breaks down in the tank rather than disappearing.
