My pufferfish won't eat flakes. Is it stressed or needs new food?

They may be stressed from the trip, the water may be too cold (low temps can affect appetite in fish) or the water chemistry may be off. Consider a partial water change. Use only conditioned water that is temperature matched to prevent further stress or shock. The fish food is fine. They will likely eat it once conditions are corrected and they settle down.

Thanks for reaching out about your pufferfish. Meal worms are bags of fat and should be used as treats only. Frozen thawed tilapia is okay, but no bones thus a reverse calcium-phosphorus ratio. Ghost shrimp okay, live feeder fish okay but pufferfish not super fast. Small clams or snails are a good source as also require chewing to get into. Pufferfish have dentition that can overgrow is not chewing a lot. Good luck.

Hello, I recommend checking water quality parameters first for any fish displaying abnormal behavior. For starters, I'd recommend keeping your fish in a larger tank as it is much easier to keep the water clean over time. This website is a good reference for basic betta fish care: https://bettafish.org/care/ I hope this helps. Thanks for using PetCoach.

Check water chemistry first. Use a home test kit or submit a water sample for testing. The local Petco may do this for free or for a small fee. Aim for an absence ( 0 ppm) of ammonia and nitrites with nitrates at 20 ppm or less. Perform partial water changes, no more than 30% at a time, to stabilize chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock. Check water temp as well. Any of these can drive a fish to the surface. The "flashing" (darting about) can be due to infection (bacterial, fungal or parasites). Consider a broad spectrum antibiotic or an "all in one" product to treat multiple infections. Look in the Aquarium section of the local Petco for options. Follow label directions carefully and remove the carbon filter insert during treatment if indicated.

An immediate veterinary check up is needed. Fish may have got spiky bones in it, or may have been not in good hygiene status. Considering his age and the signs you are describing an examination is necessary to shed some light on the underlying cause of it. Antibiotics and nutritional support may be needed as well.

He may be dealing with some swim bladder issues. The swim bladder is what keeps a fish upright and controls buoyancy. Infection, poor water quality or constipation can affect the swim bladder. Perform a water change. Use aged or conditioned water that is temperature matched to prevent further stress or shock. My choice for conditioners are AmQuel and NovAqua. You can purchase them in most pet stores or fish stores. Bettas are warm water fish and do best between 78 F and 80 F. Anything below 75 F will be stressful. A small tank heater may be necessary to maintain proper temperature. Dissolve 1 teaspoon of plain aquarium salt (NOT table salt) per gallon of water in a cup of tank water and gently pour it in. This will act as a general tonic reducing stress, improving gill function and treating minor infection. Change the water daily to maintain quality and dissolve just enough salt to treat the water being replaced. Fast him for 3 days, then offer small bits of cooked, shelled green peas until defecation and swimming are normal. You can soak the bits in some garlic juice to stimulate his appetite and boost the immune system. Transition to a quality pelleted diet and fast for one day each week to maintain GI health.

Offer a varied diet including pelleted food, fresh greens and prey such as tiny crickets or earthworms. You can get prey from the pet store, do not feed wild caught insects. It may take a day or two for him to acclimate to his new environment. Keep offering fresh food daily. Be sure environmental parameters are appropriate for the species of turtle you have. This includes adequate heat, UVB lighting and water quality. If you know the species, post it in a new question or request a consultation for more detailed care information.
