Learn how to care for Marine FOWLR Aquariums. These tanks have easier upkeep and require less testing and supplementation than a reef tank. You can keep many fish who would generally consume corals and invertebrates, making it a popular setup choice for more aggressive fish.

Hi, thanks for using Boop by Petco! Poor Murray! If he keeps vomiting he needs to be seen by a Vet for medications to stop the vomiting. With hold water for 6 hours and food for 24 hours. If there is no vomiting in the 6 hours offer shallow water only sips at a time. If he holds water down off a bland diet of boiled chicken or hamburger with rice at the 24 hour mark. Feed 1 cup per 20 lbs per day. If he refuses to eat, continues to vomit and is extremely lethargic he needs to be seen. Good luck!

Thanks for reaching out. Have you tested water quality for pH, ammonia, nitrite and nitrate. Correct problems. Don't see any signs of external lesion on the pictures, except fine erosion, and possible gravid fish. A veterinary visit is probably needed to trouble shoot for disease. Randomly adding chemicals to the water could have detrimental effects. Good luck.

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.

It is possible that she has a swim bladder disorder. Many things can cause this, only some of them reversible. Try feeding her peas for the next few days and see if that helps. If it does, then include them in her diet several times a week.

Food, genetics and stress can all affect colors. There are color enhancing diets that you can buy. Maintaining pristine water quality and stable chemistry will limit stress. If the fish has muted colors due to genetics, there is nothing to be done. As far as being "shy", this can be due to anything that is stressful or potential illness or injury. This would require and exam to diagnose.
