Insectivore Weekend Blocks 24g
Drop it in before you leave and your fish are fed till you're back. Insectivore Weekend Blocks are a slow-release feeding block built from black soldier fly larvae meal and mealworm meal rather than the plaster-based fillers used in many holiday feeders. The pack of four 24 g blocks releases food gradually as fish actively feed on it, covering a short trip without dumping nutrient load into the tank all at once.
Key features
- Real insect protein, not plaster – built on black soldier fly larvae meal and mealworm meal, with zeolite included to help manage water quality as the block breaks down.
- Releases food as fish feed – not a fixed-rate dissolve, so it doesn't cloud the tank or spike waste the way some holiday feeders do.
- Pack of 4 x 24 g blocks – one block covers a weekend away, with three spares for next time.
- 47% crude protein – in line with the Tropical Granules, so fish aren't dropping condition over a short trip.
- Insectivore also makes a Holiday Block (1 x 33 g) rated for trips up to 14 days, for longer absences than this pack is built for.

How to use
Place one block in the aquarium before you leave. It dissolves gradually, releasing food as fish actively feed on it rather than all at once. Remove any remaining block material once you're back. It's worth testing a block before you travel to see how quickly it breaks down in your particular water.

Common questions
How is this different from a regular flake or granule feed?
It's a slow-release block rather than a daily feed – designed to sit in the tank and release food gradually over several days while you're away, not to be dosed at each feeding.
How many blocks come in the pack, and how long does each one last?
Four 24 g blocks per pack. One block is rated for roughly 3–4 days, covering a typical weekend trip.
What if I'm away longer than 4 days?
Step up to Insectivore's Holiday Block (1 x 33 g), rated for trips up to 14 days.
Will it cloud the water?
It's designed to release food as fish feed on it rather than dissolving at a fixed rate, which limits the waste load compared with feeders that break down regardless of whether anything eats them.
Is it safe for a mixed community tank?
Yes – it's rated for general community stocking of 15–20 fish in freshwater or marine tanks.
