The school's accounts come first
Update your new address and phone number with your fish shop and any aquatic vet, redirect food and supply deliveries, and replace the tank's sitter and emergency sheet. Tiger barbs are kept as a school, so their paperwork describes the group — its size, its tank mates, its water — and a house move changes the setting for all three. The updates are quick individually, but skipped together they leave a chain of small failures: food delivered to the old door, a sitter working from a sheet for the old kitchen, a shop that cannot reach you.
Write down the new water, then watch the school's behaviour against it
Tiger barbs are adaptable fish, but they are also expressive ones: a settled school cruises and spars among itself, while a stressed one sulks head-down or turns its energy on tank mates' fins. Test the new home's tap water for pH and hardness and record the readings in the school's notes next to the old supply's. Barbs do well across a fairly wide range, so the value of the written numbers is comparison — if the school's behaviour changes in the new house, you can check in seconds whether the water changed with the address or whether something else needs attention.
Use the move to correct the school size and tank mate list
Counting tiger barbs in a running tank is a losing game; they are fast, similar-looking and constantly crossing paths. In the drained moving tank you can finally count them properly, and the true figure belongs in the stocking record, because tiger barb behaviour is a numbers story: a school of eight or more mostly squabbles internally, while a group dwindled to three or four is the classic setup for fin-nipping aimed at other species. Update the tank mate list at the same time, noting any long-finned tank mates, so the written record reflects the community as it actually is after the move, not as it was when the tank was first stocked.
Give the new sitter sheet the barb-specific warnings
Rewrite the helper sheet with your new address and the new local emergency contact, and include what a sitter needs to know about tiger barbs specifically: feed the whole school at once so the boldest fish do not monopolise it, expect boisterous chasing within the school as normal, and report any tank mate hiding constantly or showing ragged fins. Add the new house's practical layout — food storage, test kit, which sockets run the filter and heater — because everything a regular helper knew by habit at the old address has moved.
Settle shop registration and deliveries in the new area
Confirm that frozen and dry food deliveries carry the new address, and if you are registering with a fish shop nearer the new home, note the school's origin and how long you have kept it in your own records before the trail goes cold. If a maintenance service looks after the tank, its visit notes and contract need the new address and any entry arrangements for the property, and your own emergency contact list should name someone near the new house who can reach the tank quickly in a power cut.
With the school counted, the water readings filed and the sitter sheet rewritten for the new address, KinsLe's Pet Passport keeps a tiger barb school's records in one packet that can be passed to whoever needs it.
