Learn how to target feed bottom dwelling fish and shrimp with a step-by-step method that keeps food where it belongs and reduces waste.

Quick answer

Target feeding means delivering food directly to the bottom zone instead of broadcasting it across the surface. Use a dedicated feeding tube or a ceramic shrimp tube placed near the substrate, drop in sinking food, and remove leftovers after 30–60 minutes. This keeps food available to corydoras, loaches, and shrimp while reducing waste and water quality problems.

Why target feeding beats broadcast feeding

When you sprinkle food across the surface, much of it drifts into the filter intake or decomposes in the water column before it reaches the substrate. Bottom dwellers like corydoras and shrimp are slow, deliberate feeders that need time to find and eat their food. Target feeding places food where they already search, so they get a full meal without competing with mid-water fish. It also lets you see exactly how much is eaten, which is the single best way to avoid overfeeding.

Choose the right delivery tool for your setup

A dedicated feeding tube—often a length of rigid tubing with a funnel—lets you drop sinking pellets or wafers straight to the substrate without them scattering. For shrimp, a ceramic shrimp tube serves double duty: it is a hiding spot and a feeding station where biofilm and supplementary food collect. If you keep corydoras in a tank with strong flow, position the tube in a calmer corner so food stays put. The Hobby Genius Fish Trap is not a feeding tool, but it is useful when you need to move a fish temporarily for a health check or to rehome it—something that comes up when feeding routines reveal a fish that is not eating.

Match food type to the species you are feeding

Corydoras are omnivores that need sinking pellets or wafers that soften quickly; they will not reliably take floating flakes. Shrimp are grazers that do best with biofilm, blanched vegetables, and specialized shrimp foods that sink. Loaches and plecos may need larger wafers or fresh vegetables weighted down. The key is that the food must reach the bottom within a minute or two—if it floats for longer, it is the wrong food or the wrong delivery method for your tank.

Step-by-step target feeding routine

Step 1: Pick a consistent feeding spot: Choose a corner or open area near the front glass where you can see the substrate. Avoid placing it directly under the filter outlet or return, where flow will push food away. Checkpoint: after your first feed, the food should stay within a few inches of where you dropped it. If it drifts, move the spot.
Step 2: Set up your delivery tool: For pellets and wafers, use a feeding tube that reaches within an inch of the substrate. For shrimp, place a ceramic tube like Hugo Shrimp Tubes Grey on the substrate—shrimp will graze on it and you can drop food nearby. Common mistake: using a short tube that releases food too high, letting mid-water fish intercept it before it sinks.
Step 3: Feed a measured amount once daily: Drop only as much sinking food as your bottom dwellers can consume in 30–60 minutes. For a group of six corydoras, start with two or three small wafers; for a shrimp colony, a single blanched vegetable slice or a few shrimp pellets. Checkpoint: if food remains after an hour, you are overfeeding. Remove leftovers with a siphon or net.
Step 4: Observe who actually eats: Watch for 10 minutes after feeding. Corydoras should actively root through the substrate; shrimp should gather on the food. If a fish hangs back or looks thin, it may be ill or bullied. If a fish needs to be removed for treatment or rehoming, the Hobby Genius Fish Trap lets you catch it without nets, reducing stress on the whole tank.
Step 5: Remove uneaten food and reset: After 30–60 minutes, siphon or net out any remaining food. Rinse your feeding tube or ceramic tube in tank water during your next water change to prevent biofilm buildup that can clog it. Common mistake: leaving food overnight. It decays, raises ammonia, and can harm shrimp and bottom-dwelling fish.

Products that support target feeding

Hobby Genius Fish Trap: Hobby Genius Fish Trap is designed to easily and efficiently capture unwanted or elusive fish without the need for nets, using a bait-and-place method. If target feeding reveals a fish that is not eating or needs relocation, this trap lets you catch it with less stress than chasing it with a net.
Hugo Shrimp Tubes Grey: Hugo Shrimp Tubes Grey are ceramic, water-neutral, and safe for shrimp and crabs, providing a safe hiding place that reduces stress and encourages natural behaviour. They can also be used to attach mosses or small Bucephalandras. Placed near the substrate, these tubes create a dedicated feeding and hiding zone for shrimp, so food lands where shrimp already graze instead of dispersing into the water column.
