Before you buy any fish, you will need to set up the tank. A basic set up includes: a tank, filter, hood/light, heater, gravel and some decor. The tank should run without fish for at least 4 to 6 weeks. This gives it time to cycle. The Nitrogen Cycle is critical to the health of the tank and any fish you will be keeping. During this time, beneficial bacterial will populate the filter and substrate (gravel). These bacteria will be responsible for breaking down fish wastes and other wastes (uneaten food, dead plants, etc.). You will need a home test kit to monitor water chemistry (ammonia, nitrites, nitrates, pH) or you will have to submit water samples for testing. Most pet stores will do this for free or for a small fee. At first, you will see high levels of ammonia and nitrites. Over time, as bacteria grow, these levels will drop. When ammonia and nitrites are at 0 ppm and nitrates are below 20 ppm, you can consider adding fish. Regular (every 1 or 2 weeks) partial water changes as we

Thanks for reaching out about Timothy & Lola. Have you tested the water for pH, ammonia, nitrites and nitrates? Correct any problems. Adding non-iodized salt (aquarium salt) at 1 tablespoon per 10 gallons can reduce osmotic stress but is probably not a treatment for fin rot. If fin/tail erosions progress, antibiotics might be needed, therefore a veterinary visit. Good luck.

Anytime there is an unexpected loss of fish, water chemistry should be checked. Use a home test kit ( https://www.petco.com/shop/en/petcostore/product/api-freshwater-master-test-kit# ) or submit a water sample for testing. Most pet stores will do this for free or for a small fee. Confirm an absence ( 0 ppm ) of ammonia and nitrites with a nitrate level of 20 ppm. pH can range between 6.5 and 8, water temp should be 65 F to 75 F. If chemistry and water quality are within normal parameters, then illness or aggression would be other reasons for the loss. It is always recommended to quarantine fish in a separate tank for 2-4 weeks prior to adding them to the main tank. During this time, they can be treating for infection or parasites. I am sorry for the loss of your fish.

The safest treatment would be a temporary increase in water temperature and some plain aquarium salt (NOT table salt). Ich is very sensitive to temperature. Gradually increase water temperature, by no more than 1 degree F per hour, up to 86 F. Hold it at that temperature for at least 2weeks. This will speed up the life cycle and prevent reproduction. You can perform partial water changes (30%) and vacuum the substrate during treatment. Use only aged or conditioned water that is temperature matched to prevent stress or shock. An airstone should be used to increase oxygenation since warm water does not hold as much oxygen as cooler water. This could affect some the fish. Aquarium salt can be dissolved into the tank at 1-2 teaspoons per gallon of water. Dissolve it in a cup of tank water then pour it gently into the tank. When performing water changes, treat only the amount of water being replaced with salt, not the entire tank volume. After 2 weeks, gradually decrease water temperatur

Check the water chemistry. The discoloration could be due to elevated ammonia levels which can cause "burns". 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 20ppm or less. Perform partial water changes to stabilize chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock. The Neons (blue fish) appear to be infected with Ich, a parasite. Treatment is possible with commercial products found in the local Petco. Follow label directions carefully. You will need to treat the entire tank until all traces are gone. Removing a lump from your fish on your own is never recommended. You can cause severe injury. Most broad spectrum antibiotics (Kanaplex, Maracyn, Maracyn 2, etc.) found in the aquarium section of the local Petco should help treat or prevent infection. Choose one and follow label d
