Hardy fish still deserve current paperwork
Zebra danios tolerate a wide range of conditions, which is exactly why their records tend to be the stalest in the house — nothing has ever forced an update. A move is the forcing event: change your address and phone number with your fish shop and any aquatic vet, redirect food and supply deliveries, and rewrite the tank's emergency and sitter sheet. The danios will likely sail through the move itself; the paperwork is about making sure everyone else — shop, sitter, vet — is working from the new facts rather than the old ones.
File a water baseline anyway
Test the new home's tap water for pH and hardness and write the results into the danios' notes alongside a line on the new tank position and room temperature. Zebra danios come from flowing streams and are comfortable in cooler, moving water, so an unheated tank in a bright new room can sit warmer than the old setup did. A written baseline costs five minutes and pays off if the school's behaviour changes in the following weeks — constant surface-hanging or loss of their usual frantic energy can then be checked against recorded numbers instead of shrugged off because danios are supposed to be indestructible.
Count the school and separate out the long-fins in writing
Danios in a running tank are a streaking shoal that defeats any attempt at a census, so count them in the drained moving tank and put the real number in the stocking record. If your school includes the long-finned variety, list those fish separately in the notes: their trailing fins are the first thing damaged in transport bags and the first target if a tank mate turns nippy in the stress of a new layout. A written count and a fin note give you, a sitter or a shop a fixed reference for spotting a loss or an injury in the settling-in period.
Rewrite the helper sheet for fish that jump
The new sitter sheet needs your new address, a genuinely local emergency contact, and the danio-specific essentials: the tank lid must stay fully closed because danios are committed jumpers, especially in the first days in a new room, and the school should be fed little and often rather than in one heavy scatter that fouls the water. Add where the food and test kit live in the new house and which sockets run the filter, since a helper's old mental map of your kitchen cupboards and socket layout left with the old house.
Update shops, services and delivery addresses in the new area
Confirm every recurring delivery — food, filter media, water conditioner — now points at the new address, and register the school with a nearer fish shop if you have moved away from your old one, noting the danios' source and time with you in your own records first. If a maintenance company services the tank, its contract and visit sheet need the new address, the tank's new position in the house and any access codes for the property.
With the count corrected, the water baseline filed and the helper sheet rewritten around their jumping habit, KinsLe's Pet Passport gathers a zebra danio school's paperwork into a single packet that stays accurate wherever the tank goes next.
