I went on vacation and put a vacation feeder in the tank when I came home his tank was a sandy color. After cleaning his tank complete I put him back in and after that he hasn't been the same going on a week with out eating. What did I do wrong? Now
Check the water chemistry. Confirm ammonia and nitrite levels are 0.25ppm or less and nitrates are 40ppm or less. Use a liquid test kit or submit a sample for testing. Most pet stores or aquarists will do this for free or for a small fee. Partial water changes, about 30% can be done to decrease high levels. Use only aged or conditioned water that is temperature matched to prevent further stress or shock. My preferences for water conditioning are AmQuel Plus and NovAqua in addition to StressCoat. Confirm water temperature between 78F and 80F. You can soak pellets in some garlic juice to stimulate his appetite.

My fish is acting sick. He is not really eating and he keeps going to the surface to breathe . He is also getting these little what looks like panic attacks and swims very fast and even hits his head constantly on the edges of his tank. I started to
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.

I have a 20 gallon tank and my fish keep multiplying I have way too many fish for my tank.I have guppy fish Some with pretty colorful tails . How can I give some of them away in my area ?
Hello and welcome to Boop by Petco. You can try a few different routes to see if anyone would like some of your fish. You can post on Kijiji, or you can go around to your local pet stores and vet clinics and let them know you have free fish for good homes. Pet stores might be able to help you out if they have a bigger tank. You could also put up flyers. Best of luck finding good homes for your fish.

hi, I need some help with water condition of my fish tank. I’ve recently got 6 new fish and added in my 10 gallon fish tank three days ago. I did set up my tank for 48 hours before adding fish but now the water gets cloudy with tiny air bubbles on th
48 hours is not long enough for a tank to properly cycle. Several weeks to a couple months are needed for beneficial bacteria to populate the substrate and filter. These bacteria break down wastes (ammonia, nitrites, nitrates) that are harmful to fish and can promote bacterial blooms resulting in cloudy water. The overfeeding likely contributed to the bacterial bloom. You can cycle with or without fish, however cycling with fish will increase the risk of loss. You'll need to monitor chemistry using a liquid test kit. The kits with strips are not as accurate. Perform partial water changes, no more than 25%, every few days or if ammonia levels begin to affect fish. Use only aged or conditioned water that is temperature matched to prevent stress or shock. Feed them every other day. Normally, you would add one fish at a time but that isn't possible for you now. Monitor chemistry and perform water changes until ammonia and nitrites are 0.25ppm or less and nitrates are 40ppm or less. This
