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.

We bought my son 5 cherry barbs earlier today along with a tank rocks and some items for the fish to hide in. About 9:30 tonight we checked on the fish and unfortunately they had all died. We followed YouTube videos and read articles about how to tra
I'm sorry for the loss of your fish. If the tank was a "new" tank, it likely was not sufficiently cycled. The fish may have died after being exposed to high levels of ammonia or nitrites. A fish tank should be cycled for 4-6 weeks before fish are added. This allows time for beneficial bacteria to populate the filter and substrate. These bacteria are responsible for breaking down wastes (fish waste, decaying plants, uneaten food) to prevent a buildup of ammonia, nitrites and nitrates. A tank can be cycled with fish, however this requires close monitoring of water chemistry and frequent partial water changes to stabilize chemistry and maintain water quality. Cycling with fish increases the risk of fish loss.

hello, I just got a kitten she is one month old. I just want to know what to get for her when i go shopping tomorrow to go get stuff from your store.
Congratulations!! I would recommend making sure you get kitten appropriate toys, two litter boxes and kitten food. At 1 month of age I would recommend a wet kitten food. I would also recommend clumping litter for her. You can always get her other fun stuff like a soft bed for her. I would hold off on any treats until she gets used to her new home. Thank you for using Boop by Petco.

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

hi! I have gold fish in a tank and after doing a 20% water change my fish seems to be in shock just sitting at the bottom of the tank... could it be the PH level change? please help me!
It may be the pH change or other change in water chemistry. Use a home test kit to check water quality. Make adjustments as indicated. It may also be a response to a temperature change. Check water temperature and increase the heat if necessary, just don't forget to turn it down or off once the temp is within range.
