A cichlid off his food is a sign with a long list of possible causes, and aquatic vets work through that list with numbers and history, not with a look through the glass alone. Many aquatic consultations begin by phone or video, which makes your preparation the examination's first stage. Gather the readings, the timeline and the film before you call, and the advice you get back will be about your fish rather than about cichlids in general.
Test the Water and Write the Numbers Down
Use your test kit on the day you contact the vet, not last week's figures, and record temperature, ammonia, nitrite, nitrate and the acidity reading, exactly as the kit reports them. Note also when the previous water change happened, how much was replaced, when the filter was last cleaned or its media changed, and whether the heater has been behaving.
Write the tank's size, its full stock list with sizes, and how long each fish has been in it. A vet reads a stopped-eating report very differently in a settled tank of two years than in a crowded tank stocked last month, and aggression from tankmates is judged against who shares the water.
The Feeding and Behaviour Timeline
Pin down when he last ate with certainty, and what normally happens at feeding: where he feeds in the water, how fast he arrives, what he is offered and what he still refuses. Describe what you see now in plain terms: food ignored, food taken and spat out, or interest shown from a hiding place without emerging. Add waste changes, including paler or trailing waste, breathing rate while resting, clamped or frayed fins, colour darkening or paling, scratching against decor, and where he spends the day compared with his usual territory.
Film a feeding attempt and a resting period on your phone. Belly shape, whether hollow, normal or swollen, shows clearly on video, and the vet can judge swimming posture and breathing from a clip in a way a description rarely matches. Note any recent additions, moved rocks, redecorated corners, building work near the tank, or a tankmate who has begun chasing him.
Questions to Ask the Vet
Ask which conditions or causes could fit this combination of signs, and what would help distinguish between them. Ask what you should check or photograph next, whether they want a separate water sample brought in a clean container, and whether they need to see the fish or can advise from the readings and film. Ask about feeding during the wait: whether to keep offering his normal food, change nothing for now, or pause, and follow that instruction rather than improvising tempting extras.
Ask which developments should trigger urgent contact: rapid breathing, loss of balance, a swelling belly, stringy waste with weight loss, or other tankmates stopping eating. One fish off food in a tank where readings are clean is one problem; several fish off food points the questions in another direction, and the vet will want to know which picture yours is.
Keep the Tank File Current
After the call, write down the advice, the readings it was based on and the review point you agreed, and keep testing on the rhythm the vet set. Small daily notes on who ate, who hid and how readings moved turn a vague worry into a trend the vet can act on at the next call.
Dated and filed through KinsLe, a Pet Passport record keeps each set of water figures beside the stock changes and feeding notes, so advice a month apart still rests on one continuous tank history.
