The short answer for espei rasboras
Feed espei rasboras once or twice a day, each time offering fine food the school finishes within about two minutes. Two modest meals support growing fish and the strongest copper colour; one well-judged daily meal maintains adults in a planted tank where they also pick at tiny life among the leaves. The pattern to avoid is the single heavy feeding — espeis are grazers on small prey, not gorge-and-rest feeders, and their slim bodies show overload quickly.
Copper fish, small prey
The espei rasbora — the lambchop rasbora, named for the dark wedge along its copper flank — feeds in nature on small insects, larvae, and zooplankton in slow, plant-choked water. In the aquarium that translates to crushed flake, micro-pellets, and small live or frozen foods: baby brine shrimp, daphnia, and mosquito larvae are taken eagerly and deepen the orange-copper tones. Particles should be genuinely small; espeis will work at an oversized flake briefly, but most of it ends up shredded into the water column as waste. Slow-sinking delivery matters too, because this school feeds most confidently from the upper-middle layer as food drifts down through it.
Scatter so the wedge includes everyone
Espei schools hold a loose hierarchy at feeding time, with the boldest fish rising first directly under the food. Sprinkle the meal along a line rather than a point, and let gentle flow carry it, so fish at the school's edges intercept pieces without pushing through the centre. In a community tank, espeis are peaceful but not pushy; if they share with barbs or guppies, watch a few full feedings to be sure the rasboras' bellies fill too. A pipette puff of food into the plants where shyer espeis hold station is a simple fix when they are not.
Slim by design — reading their condition
Do not judge espeis against plump-bodied fish. A healthy espei is streamlined, deepest just behind the gills, with a belly that rounds subtly after a meal and flattens within the hour. Persistent roundness across the school, food reaching the substrate, and fast-fouling water all say the two-minute rule has quietly stretched. At the other end, hollow bellies and a fading of the copper wash — espeis go dull and greyish when underfed or stressed — say the pinch needs a small increase or competition needs addressing.
When the school goes off food
Espeis are sensitive barometers of a tank: a school that stops rising to feed is often reacting to a water shift, so test ammonia, nitrite, and temperature before changing the menu. One fish hanging apart, darkening, and refusing meals while the school feeds normally deserves same-day advice from an aquatic veterinarian or knowledgeable fish shop, because small rasboras decline quickly once they stop eating. Never respond by tipping in extra food — in a planted rasbora tank, uneaten food is tomorrow's water problem.
A school feed with a name on it
Rasbora feedings are quick, quiet events, and in a multi-person household that makes them easy to duplicate. Put a name against each day's feed and let completion show. KinsLe's Care Teams sets that pattern for this tank: the espei feeding is an assigned duty, and when the helper marks it done, the timestamp tells everyone else the copper school has already had its two minutes.
