What's the best food for a picky glass catfish that won't eat?

There may be a variety of causes for it: - When introducing new food you have not fed to your fish before it is best not to feed them for a day. -You should ideally feed bloodworms only if your fishes are carnivorous or omnivorous -buy good quality ones. - in my experience many fishes do not like frozen and thawed ones.

The fish pictured are incompatible in the same tank. Angelfish (black ones) are tropical fish and do best in temps between 73 F and 84 F. Goldfish (white and orange) are cold water fish thriving in temps between 65 F and 72 F. It also appears as if one of your angels has some damage to a tail fin. This is typically due to fin nipping by other fish. You will need to remove either the angels or the goldfish and place them in a different tank. Check the water chemistry for elevated levels of ammonia or nitrites. This can occur in an uncycled tank or a tank that is overstocked. Partial water changes (30-50%) daily can decrease toxin levels. Use only aged or conditioned water that is temperature matched to prevent stress or shock. Confirm your filter is rated for at least twice the water volume of the tank, especially for the goldfish. The links below provide additional information for care of angels and goldfish. http://aquariumtidings.com/angelfish-care/ http://aquariumtidings.com/all-about-goldfish-how-to-care-for-a-goldfish-fish-at-home/

Most puffers will not eat flakes or pellets. They need live or frozen foods. They also require hard foods to keep their teeth worn down. The local Petco will likely have these foods in stock. If the tank is overstocked, he may be stressed. He may also have an infection (bacterial, fungal or parasites) that are causing his symptoms. Ideally, a new fish should be quarantined for 2-4 weeks before being introduced to the main tank.

The Sharks and Tetras can eat a high quality flake food every day. Brine shrimp (either live or frozen) and blood worms can also be offered. Tetra and Hikari are my own recommendations. The Pleco can eat fresh greens or vegetables. Remove any uneaten food after 24 hours to prevent fouling the water. Sinking wafers or pellets can also be offered.

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.

Check the water temperature. This species does best between 68 F and 77 F. Low temps can affect appetite in fish. He may be near the heater for warmth. Check the water chemistry as well. Use a home test kit or submit a water sample for testing. Most pet stores will do this for free or for a small fee. Aim for 0 ppm ammonia and nitrites with a nitrate level of 20 ppm or less. Partial water changes can be done to stabilize chemistry if indicated. Use only aged or conditioned water that is temperature matched to prevent further stress or shock. If it is a "new" tank, there may not be enough food/algae on the bottom for it. Use sinking pellets or toss in some vegetables or greens. Be sure to remove any uneaten food after 24 hours to prevent it from fouling the water.

Often providing a wide variety of foods and flavors actually promotes picky eating. If they are otherwise well I recommend you pick a one flavor formulation of high quality brand sch as hills science plan or royal canin and put down one sachet at a time, adding more if this is eaten. Cats are grazing feeders and are likely to prefer little and often, as long a s a complete balanced dry food and fresh water is available at all times they should self regulate their own food intake. Be sure to have more feed and particularly water stations than you have cats to ensure there is no territorial bullying preventing any of them from eating when they would like to
