Feeding in the first month: learn to assess portions

For a new Neocaridina group, start with a small visible portion of suitable shrimp food and observe actual uptake. Use an established tank with grazing surfaces. Extra powder does not make a bare tank safe or adequately nutritious. Equally, brown surface growth does not prove that every stocking level has sufficient food.

Record portions, uptake and leftovers

• Begin with one food and a visible feeding spot. Record a repeatable portion, such as a particular piece of the same pellet.
• Check after offering and again later. Consider that food’s instructions and breakdown rate. Remove clearly uneaten or disintegrating leftovers.
• Check who eats: missing food may have been taken by fish or snails. Do not increase the ration solely because the bottom looks empty.
• Change one variable at a time: portion or interval. Assess subsequent feeds, colony growth and juveniles.

No established schedule requires every starter group to feed on alternate days or fast on arrival day. Do not keep adding food to lure newly arrived animals out of hiding. Check conditions and allow them to settle. Persistent refusal to feed or deterioration warrants investigation beyond food choice.

What this routine covers

Neocaridina graze on biofilm and detritus among other foods. Bee/Taiwan Bee and Cardinal portions must likewise fit their actual setup and population. Fan shrimp require a separate feeding approach: usable suspended particles in moving water, not simply a visible portion on the bottom.

Young shrimp need accessible fine grazing surfaces. Do not scatter unlimited powder because the animals are small. Choose appropriate food; protein percentage alone does not explain a moulting problem. Leaves remain decomposing organic matter and are not guaranteed complete nutrition.

If water quality deteriorates

Cloudiness, rotting leftovers, abnormal behaviour or detectable ammonia/nitrite calls for investigation. Remove excess material, check filtration and aeration and follow the nitrogen route in the water guide. A larger ration does not solve unexplained inactivity. Record a working routine before relying on a sitter or feeder.

The observation routine is our practical judgement, not an experimentally established universal dose or schedule. The Aqueon source is used only for fan shrimp capturing suspended food from a current.
