Aquatic Animal Care

What they do

This specialty is centered on the animals rather than the build or the heavy servicing. Carers feed to a set plan — by species, amount, and frequency — and understand why more is not kinder: uneaten food decays, ammonia rises, and water quality falls fast in a closed system. They vary foods appropriately, from staple prepared diets to frozen or live foods and vegetable matter for species that graze, and they target-feed shy or bottom-dwelling animals that lose out at surface scrambles.

Observation is the other half of the job. A good carer knows normal behavior for the species in front of them and notices the early departures: a fish isolating itself, clamped fins, rapid gill movement, loss of color, white spots, or a shrimp or snail staying inactive. They run basic water tests when behavior changes, because in aquatics most apparent illness starts with water — temperature, ammonia, nitrite, pH, or, in marine systems, salinity — and correcting the environment comes before reaching for any treatment.

Holiday and absence cover is a large part of the work. Carers follow written instructions for feeding, lighting, top-offs to replace evaporation, filter checks, and what to do if a pump stops or the power trips. They resist well-meant extras from neighbors — no bonus handfuls of food — and report test results and behavior while you are away, rather than only if something dies.

That focus separates this service from aquarium maintenance, which owns filtration servicing and water changes, and from installation. An aquatic carer may do small top-offs and basic checks, but deep cleans, equipment replacement, and clinical treatment sit with maintenance providers and aquatic veterinarians respectively.

Services you can expect

• Daily and holiday feeding to a written plan
• Species-appropriate diet rotation and target feeding
• Behavior and health observation with reporting
• Basic water testing and temperature checks
• Evaporation top-offs and lighting management
• New arrival acclimation support
• Quarantine tank feeding and observation
• Fry and juvenile feeding schedules
• Owner coaching on feeding and observation

What to expect

• Feeding measured to the plan, with leftovers noticed and reported rather than fed over
• A daily note on behavior, appetite, and any animal not seen
• Basic tests run promptly when behavior changes, with results shared the same day
• Instructions followed exactly during holiday cover — no improvisation with food or treatments
• Clear escalation: water problem to maintenance, suspected illness to an aquatic vet

How to choose

• Choose a carer who has kept or cared for your kinds of animals — marine, tropical, coldwater, and invertebrates differ greatly
• Ask how they decide whether a behavior change is a water problem first
• Check they will feed to measure and will refuse extra feeding requests from others in the house
• Look for written visit reports, not just a verbal all-fine
• Confirm cover arrangements for long trips, including a backup person

Questions to ask

• Which species and systems have you cared for before?
• How do you portion food, and what do you do about uneaten food?
• What behavior changes do you watch for, and what tests would you run?
• Will you add any treatment or new food without asking me first?
• How will you report to me while I am away?
• Who do you call if a filter stops or a fish looks seriously ill?

Red flags

• Feeding by handful with no measure and no interest in your plan
• Treating every sick fish with a general remedy without testing the water
• No observation notes — unable to say which animals ate or appeared
• Willingness to add new fish to your tank as a surprise or favor
• No backup plan for equipment failure during holiday cover

What affects the price

• Number of tanks and animals covered
• Visit frequency and length of absence
• Marine, reef, or specialist species complexity
• Target feeding, fry, or quarantine schedules required
• Testing and reporting level expected
• Travel distance and out-of-hours cover
