First check of the day: temperature, surface, fish
A betta's week begins the same way every day of it does, with the morning check before any food appears. Read the thermometer against the heater's behaviour, because a betta kept warm is active and coloured while a quietly cooling tank produces a fish who still eats but has begun his decline. Look at the betta himself next: fins carried open, a patrol of his usual route, interest in you at the glass. Break up any surface film with a clean fingertip or a skim so he can breathe and feed at the surface comfortably, and only then offer breakfast, removing within minutes whatever he leaves, since a betta's ration is measured in individual pellets and every missed one becomes tank waste by afternoon.
Midweek: plants, glass, and the quiet jobs
The middle of a betta's week carries the small maintenance that keeps the main cleaning day short. Inspect plant leaves for tears and die-back, snipping a damaged leaf at its base rather than letting it rot against the substrate, and check that resting leaves near the surface still hold their position, since a betta sleeps on them and a collapsed perch changes his nights. Wipe the front glass inside with a soft pad so the end-of-week fin check will be readable, top off evaporation with conditioned water, and confirm the filter outflow still moves gently. None of this requires catching, moving, or even much disturbing the fish, which is precisely the point of spreading the week's work instead of stacking it into one long intrusion.
The main event: one partial change in a set order
On the week's set cleaning day, a betta's change runs in an order that protects him at each step. Unplug nothing in a panic and move nothing he lives in; begin by siphoning debris from around decor and plant bases into your dedicated fish-only bucket, hovering above the substrate so his mapped territory stays intact. Wipe the remaining glass while the level is lowered, then rinse the filter sponge in the bucket of removed water and return it. Refill slowly with conditioned water matched to the tank's temperature, poured over a dish or your clean hand so the stream never shoves him across the tank, and finish by confirming heater and filter are running and his surface is clear before the light goes off on schedule.
Last task of the week: the fin inspection and reset
The betta week closes with a deliberate fin and scale inspection under the tank's brightest light. Turn a small treat to your advantage and watch him display as he feeds: look for new tears that would indict a piece of decor, dark edges that would indict last week's water, and any scale out of place from a collision. Note what you find, however briefly, because a fin that frays a little further each inspection is telling a story that one glance cannot. Top off the water, set out the next week's conditioned supply if you prepare it ahead, and leave him to a normal evening. On KinsLe, Care Teams assigns dawn checks to the early riser and cleaning day to whoever is around, so no stage of the week depends on memory alone.
