Why baby shrimp change how you clean
Baby shrimp are only a few millimetres long, nearly transparent, and they spend their first weeks grazing biofilm on moss, sponge filters, leaf litter and the top layer of substrate — exactly the places a normal clean disturbs most. A standard gravel vacuum that is perfectly safe for fish will pull shrimplets straight through the tube, and a fast, large water change can shock them because their small bodies are far more sensitive to sudden shifts in temperature and water chemistry than the adults sharing the tank. The goal here is not a spotless aquarium; it is removing waste and refreshing water while leaving the babies' grazing surfaces and hiding cover almost completely untouched.
The tools that replace your usual kit
Swap the wide siphon for a length of airline tubing, or fit a piece of fine mesh or clean stocking over the intake, which lets water and loose debris through but stops a shrimplet being drawn in. Always drain into a light-coloured bucket rather than straight into a sink: against a pale background you can spot any tiny shrimp that did get pulled through, pipette them out, and return them to the tank before the water is thrown away. Keep a turkey baster beside the tank for spot-cleaning single piles of waste, and service the sponge filter — the safest filter type in a breeding tank — by squeezing it gently in removed tank water rather than replacing it, since its surfaces feed the babies too.
A cleaning routine that protects the nursery
Work in small passes instead of one big session. Draw off a modest amount of water slowly, hovering the covered intake just above the substrate to lift loose mulm without digging in, and leave planted and mossy areas alone altogether, because the biofilm growing there is the shrimplets' main food. Wipe algae from one pane of glass at a time so the shrimp keep their grazing surfaces on the others, and never strip out every decoration in a single visit. Refill by dripping fresh, dechlorinated, temperature-matched water in slowly over an hour or more; that gradual return is the single biggest stress-saver in a baby shrimp tank, because it turns a sudden chemical change into one their small bodies can track.
What to watch after each clean
In the hours after cleaning, look for babies gathering at the water surface or clinging near the filter outflow, which can signal the new water differs too much from the old, and check the discard bucket a second time under a good light before emptying it. A few pale empty moults on the substrate are normal and can be left where they fall, since shrimp eat them to recover minerals. If you find several dead babies after a clean, make the next change smaller and slower rather than more thorough. Recording each water change and what you noticed in KinsLe through Care Teams lets family members repeat the same gentle pattern for the shrimp tank instead of improvising harsher methods.
