The pair question decides the packing
Most fish transport begins with the container; kribensis transport begins with a relationship. A settled, non-breeding pair often travels calmly together in one generous container with a small cave or tube inside it. The same pair in breeding condition, or a male and female whose bond is recent and argumentative, can arrive as one fish and a victim, because the cave-defending instinct that makes kribensis such devoted parents turns savage in a space neither can leave.
Judge the pair honestly before moving day. If there has been chasing, lip-locking, or one fish living at the opposite end of the tank, pack them separately in matched containers and reunite them in the new tank under observation. Pride in a famous pair bond has injured more kribensis than bad water ever did.
A cave in the container, a cave in the tank
Whether travelling alone or as a pair, give the container a short tube or small cave the fish can back into. A kribensis that can perform its instinctive retreat settles; one exposed in open water under a transparent lid spends the journey in a state of alarm. Use a rigid container with its own tank water, keep it dark and level in the cabin, and secure the lid, since a startled kribensis darts hard enough to find any gap.
Catching follows the same logic as packing. The fish will back into its tank cave and defend the door, so lift the cave, fish and all, into the transport container under water where the cave is movable. This single trick converts the worst catch in the cichlid family into the easiest, and it preserves the one object the fish values most for arrival.
Arrival should end at a cave mouth
Prepare the new tank before the fish travels, with a cave placed in a quiet corner and, ideally, the fish's original cave if it did not travel with it. Equalise temperature, mix the new water in gradually, and open the transport container beside that cave so the kribensis exits into a claimable shelter. For a pair packed separately, release the female first and let her take the cave, then add the male and watch the first meeting as you would any introduction.
Dim the lights and leave the cave corner strictly alone for the first day. Tidying fingers at the cave entrance read to a kribensis as an attack on the nursery, whether or not any eggs exist.
Settling signs and squabble signs
A settled kribensis colours up, patrols a small radius around the cave, and eats within a day. A pair reuniting well will display, shimmy, and negotiate the cave entrance together. Relentless pursuit, one fish hiding at the surface, or torn fins mean the reunion is failing; separate them again and retry with the tank's cover rearranged so the territory itself is new to both.
Test the water across the first days as you would for any moved cichlid, and feed lightly until the fish is feeding from its cave base rather than snatching and bolting.
Pair status, breeding history, and cave arrangements are the facts a future keeper or vet most needs about this fish, and KinsLe stores them in its Pet Passport so the kribensis arrives with its story as intact as its cave.
