Scissortail rasboras should be fed twice a day, with a ration a notch heartier than you would give the miniature rasbora species. These are the athletes of the rasbora group: long, silver, fork-tailed fish that scissor their black-and-white marked tails as they cruise the upper water, and a mature school covers a tank with real speed. That engine runs on regular feeding, and two meals the school clears in around two minutes will keep scissortails in hard, bright condition.
Feeding fish that live at pace
Scissortails feed where they swim, in the top third of the tank, snapping up insects and larvae at the surface in the wild. Dry food should therefore float or sink slowly: a good flake is ideal, small pellets that hang in the current work, and fast-sinking granules are a poor choice because they drop through the school's feeding zone before the fish can react. Thawed daphnia, brine shrimp, and mosquito larvae match their natural prey closely and trigger a spectacular group response as the whole school carves through the cloud.
Because scissortails bunch tightly at food, scatter each meal in a line along the front glass rather than a single drop. The dominant fish cannot guard a metre of surface, so every rasbora in the school eats, not just the fastest two.
The jumping problem at feeding time
Any scissortail feeding plan has to reckon with their one dangerous habit: they jump, powerfully, and feeding excitement or a sudden shadow over the tank can launch a fish clean through a gap in the cover. Feed with the lid or cover glass fully closed except for a feeding hatch if you have one, approach the tank steadily rather than looming suddenly, and check the floor around the tank after any startling moment, because a scissortail found quickly can often be returned unharmed. A school that repeatedly startles at feeds may be telling you the tank sits in a high-traffic spot with constant shadows crossing it.
Size, condition, and fair shares
A healthy scissortail is torpedo-shaped with a clean line from head to forked tail and a bright, flashing flank. These fish should look athletic, not filled out. If your school starts to look deep and slow, the two meals are too big; if individuals at the rear of the school look pinched while the leaders grow, the food is not being spread widely enough, and widening the drop zone matters more than adding extra feeds.
Juveniles building toward adult size appreciate the same twice-daily pattern with slightly richer frozen foods in the mix. Older, settled adults need nothing extra, and an occasional missed meal does them no harm at all, which is worth remembering before you ask a neighbour to feed generously while you are away.
Keeping count in a house full of feeders
Fast, eager fish train households to feed them, and scissortails flashing at the glass are convincing actors even twenty minutes after a meal. A written record is the only reliable memory. KinsLe's Care Teams lets you assign each scissortail feed to whoever is on duty and mark it complete with a timestamp, so the school's two daily meals stay at two and their waistlines stay athletic, even when several people share the tank.
