Hello, I bought 3 fish (2 cichlids and 1 ray) and an aquarium (90 litres) yesterday. I prepared the aquarium and put the fish inside. However there is a power shortage at the moment. The temperature of the water is fine but what can I do to increase
Hi there! The fish will probably be ok for a day, but if the power doesn't come back on, you should consider purchasing a battery-operated aerator. I highly recommend that all fish owners keep one of these on-hand for situations like this. I don't know if this person ships to Turkey, but a similar product would be fine, too: https://www.ebay.com/p/Rapala-Battery-Powered-Aerator-Model-Raertr-c/1000293148?iid=371986500727 Most fish will come to the surface for air, but they really do need dissolved oxygen to thrive. Good luck!

All of my fish died after using a product purchased at Petco called ACUREL-F. How do I get their water safe to put in new fish?
I would recommend to have the water completely changed. New water should be ideally submitted for quality testing. Most pet stores will do this for free or a nominal fee. High ammonia levels, PH imbalances may be responsible for that as well. Oxygen concentration and quality of the filters should be determined as well. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

I have a freshwater fish in my aquarium that I cannot identify. It resembles a Mosquito fish but is lighter in color, thinner, swims differently, and has what appear to be sparkles on its sides. I caught it with a net in a school of mosquito fish but
Without an image, it will be difficult to definitively identify the fish in question. It may be a wild guppy. You can request a consultation which will allow you to share images. It is not recommended to add wild caught fish to an existing aquarium without an acceptable quarantine period.

Hey! Just got a beta fish and he is swimming fine... but after I fed him, he seemed to “hyperventilate”! But then again, he’s swimming fine. Is this okay? He’ll also swim really fast at some points. Is he just nervous?
Monitor for redness, white spots or fuzzy growths on him. The swimming fast may be "flashing", which a fish with an infection will do to "scratch an itch". Maintain pristine water quality via filtration and partial water changes. Use only aged or conditioned water that is temperature matched to prevent stress or shock when performing water changes. Bettas do best between 78 F and 80 F. Monitor water chemistry to confirm 0 ppm ammonia and nitrites with nitrates at 320 ppm or less. If you don't have a home test kit, most pet stores will test water for free or for a small fee.

I have basic aquarium at home, since 2 days all are not active and seen abnormal, shark, gold, koi are all having bleeding on their body without any reason i know. Suddenly at one time continuously fishes getting die, even I changed water at overnigh
I'm sorry you are having difficulties with your aquarium. There are several issues that should be dealt with right now. They are water chemistry, aquarium size and choice/number of fish. Any new aquarium should be set up and, ideally, run empty for several weeks (usually 4-6 weeks). This is so beneficial bacteria have an opportunity to populate the substrate and filter. These bacteria are necessary to break down wastes that fish will produce. The technical phrase for this is "establishing the Nitrogen cycle". These bacteria will break down wastes into ammonia then nitrites then nitrates. Nitrates can then dissipate or be absorbed/used by live plants. In high enough concentrations, ammonia and nitrites are toxic and can kill fish. Cycling a tank with fish is possible but it increases the risk of loss. Water chemistry should be checked every few days using a liquid home test kit. A water sample can be submitted for testing , but is not as convenient as testing yourself. Most pet sto
