A siamese algae eater is the busiest fish in a planted tank, and a typical day of care means supporting a worker rather than pampering a pet. This slender fish, black stripe running nose to tail-fin, spends its hours mouthing algae off plant leaves, glass, and wood, then resting flat on its pectoral fins across a broad leaf. Your daily input is modest: watch the work, supplement the diet, and keep an eye on the manners of a fish that can grow bolder with age and size.
Morning: find him at work
A healthy algae eater is grazing within minutes of lights-on, working a leaf edge or the front glass. Look for the posture that gives the species away — propped on his fins at rest rather than stuck to the glass with a sucker mouth, which would mean a different, more troublesome fish was sold under his name. Confirm he is slim-flanked and active; a young true siamese algae eater kept busy all day is burning real energy.
Daytime: algae is a job, not a diet
The daily misunderstanding to avoid is assuming the algae is enough. In a well-kept tank there may be too little of it, especially the soft green types he prefers, and a hungry algae eater starts supplementing himself at feeding time or, worse, grazing the slime coat of slow tankmates. Your daytime role is minimal but the planning matters: keep some algae growing on the back glass and hardscape by not scrubbing every surface, and let the planted tank's light hours support that growth.
Evening: the supplementary feed
Drop in a sinking wafer, some blanched zucchini, or bottom-focused pellets as the day ends, positioned where he patrols. Frozen bloodworms occasionally keep him enthusiastic about provided food rather than tankmate-flavored food. While he eats, run the behavior audit: is he chasing other fish, fixating on a slow angelfish or discus, or hogging the resting leaves? Young fish are peaceful; a maturing one that turns pushy is a known pattern, and catching it early is a daily-observation dividend.
The weekly frame
Weekly, clean the front glass, change water, and reassess whether his algae workload and his supplement balance still match — a fat, idle algae eater needs less food and more expectation of work. In KinsLe, Care Teams divides that rhythm into named duties — the evening wafer, the weekly glass and water change — each marked complete with a timestamp, so the working fish gets supported without being overfed by two helpers on the same night.
