Address updates with the escape warning attached
A clown killifish move should send the new address and phone number to the veterinarian, the aquatic shop, and any sitter service, and each of those records deserves a short line identifying this fish as a determined jumper living at the surface. That single line changes how other people handle the tank: a sitter who knows will feed through the hatch instead of lifting the whole lid to admire the fish. Update deliveries of food and filter supplies to the new house, restate the tank's size and position on any landlord or household paperwork, and refresh the emergency sheet for the new room so the escape warning appears before any other instruction.
Lid, gaps, and surface cover written down precisely
A clown killifish can leave a tank through a gap an owner barely notices, so the moving paperwork should describe the rebuilt setup in unusual detail. Record the lid type, how it seats, and which corners or cable cut-outs are covered and with what, so a helper can verify the seal at a glance. Note where the floating plants collect and how much surface they cover, because that floating shade is both the killifish's shelter and part of its security. If the water level was dropped slightly to add a safety margin below the rim, write that in too, with the reason, so nobody helpfully tops the tank to the brim.
Soft water readings and small-food records
A clown killifish comes from slow, soft, leaf-stained forest water, and a house move may deliver a harder, brighter supply. Test the new tap water once the tank settles and record hardness and pH beside the old address readings, marking which house each set belongs to. Note how the fish are using the surface in the first weeks, since a killifish hovering lower than usual is offering information. The feeding record should name the fine foods actually used and where they are kept in the new home, because a helper offering large flakes to a small-mouthed surface feeder will conclude wrongly that the fish is not hungry.
Group composition and surface behaviour notes
A clown killifish record should describe the group as kept, not just the species in general. Note how many fish moved, whether they are kept as a pair or a small group, and which fish claims the prime floating cover, because surface territory shapes this species' daily peace. Record the usual feeding picture too: healthy clown killifish rise and pick at the surface eagerly, so a fish that stops coming up is offering the first clue something has changed. File a clear photo of the group's markings with the notes, since individual killifish can be told apart by pattern once someone knows to look.
New local contacts for a specialist nano fish
A clown killifish is a fish many general shops never stock, so the paperwork should name the source near the new home for suitable live and fine foods, and note the breeder or shop that supplied the group in case replacements or advice are needed. Refresh keyholders and the nearest backup for the new address, add the room's sockets, tap, and storage places, and file the transport notes, including whether the fish travelled with floating plant cover. Storing that specialist detail in KinsLe's Pet Passport keeps the killifish's escape plan and water record within reach of whoever cares for it next.
