Start With Whether Your Guppies Stay as Their Own Group
Guppy knowledge at a boarding service begins with grouping, because your guppies should board as their own colony in their own tank, not be tipped into a general community aquarium. Ask exactly where the group would live and what else, if anything, would share the water. A service that knows guppies keeps a boarding group separate, both to protect your fish from unfamiliar tankmates and to make sure the fish you collect are actually yours, which matters when guppies look alike and numbers shift.
Ask how they count and record the group at drop-off. A careful service notes numbers, distinctive males, and any obviously pregnant females with you present, and photographs the group as a reference. That record protects everyone later, because guppy groups genuinely change: fry are born, an elderly fish may die, and without an agreed starting picture those normal events turn into disputes at collection.
Fry and Breeding Honesty Is the Real Knowledge Test
Ask the service directly what happens when a female guppy gives birth during a stay, and judge them on the honesty of the answer. Guppies breed readily, females can carry young for weeks after contact with males, and any service promising that numbers will be identical on collection either does not know guppies or is not being straight with you. A knowledgeable service explains that fry may appear, describes the plant cover or refuge fry would use, and agrees with you in advance whether newborns join your group or are handled another way.
Follow by asking about the filter, because fry survival in a boarding tank often comes down to intake safety. Listen for sponge-covered intakes and gentle flow, and for a lid fitted tightly enough that no guppy can jump through cable gaps. A service that has actually kept guppies will raise fry safety and jumping without prompting, since both are everyday realities of the species rather than exotic edge cases.
Feeding and Water Questions for a Colony Tank
Ask what food the service gives guppies and in what form. Good answers mention small flakes or micro foods crumbled finely enough for young fish, fed in amounts the group clears in minutes, because a colony tank hides leftovers among plants where they decay unseen. If the service feeds every tank the same food from the same tub, ask how guppy portions are adjusted, and weigh a vague answer accordingly.
Ask about water testing and changes for a planted colony tank. Guppies appreciate stable conditions and steady routines, so listen for regular checks, modest partial changes, and reluctance to strip the tank down for a deep clean mid-stay, which would disturb plants, fry shelter, and the group's settled behaviour. Also ask what they would do if several guppies suddenly hid or one was found dead, and expect water testing and a call to you before any treatment is considered.
Look at Their Guppy Tanks and Agree the Updates
Visit and observe the service's own guppy or livebearer tanks. You want active fish spread through the water, plants offering real cover, clear labels, and staff who can tell males, females, and juveniles apart at a glance and talk sensibly about each group in their care. A service whose own guppy tank is bare, overcrowded, or full of fish hanging at the surface is showing you its standard.
Agree update arrangements before the stay: how often you will hear from them, whether photos show the whole planted tank, and how births or losses will be reported rather than saved up for collection day. Ask how your guppies will be caught at the end, since chasing a whole colony with a large net stresses every fish, including fry you may never see counted.
