Hi, I just got a fish from a friend and I don’t rlly know anything about that fish, it’s rlly small(about 4cm) and I want to know the breed of the fish and how to take care of it. Thanks you
Thanks for reaching out about you fish. It is believed to be a Comet goldfish. Water quality and nutrition is the key to success. Testing water parameter for pH, ammonia, nitrite and nitrate will give you guidance for a healthy environment. Purchased food should be rotated out every 3 months as vitamin C and other nutrients degrade over time. Trying to maintain water temperature can be challenging with out a heater, but most fresh water fish tolerate some changes. Good luck.

I have an angelfish and a red tail shark in a 15 gallon tank for about 4 days and they get along great. The angel fish has been almost swimming kind of lazy like almost floating and then will swim when off balance. And belly kinda looks swollen as we
Check the water chemistry and temperature. Use a home test kit or submit a water sample to test fro elevated ammonia or nitrite levels. Most pet stores will do this for free or for a small fee. Partial water changes can be done, if indicated, to stabilize chemistry and improve or maintain water quality. Ideally, you want 0 ppm ammonia and nitrites with nitrates at 20 ppm or less in a non-planted tank or 40 ppm or less in a planted tank. Use only aged or conditioned water that is temperature matched to prevent stress or shock. You'll need to keep the temp at the upper limits for Red Tails in order to keep the Angelfish comfortable. That would be in the 78F to 80 F range. Both have similar pH requirements, 6.8 to 7.5. You can fast the Angel for 2-3 days then feed bits of cooked, shelled green peas. This will usually resolve constipation and bloating. Pristine water quality may resolve the patch on your shark. Recommending a medication without more information or a clear image would be

It looks like a species of gourami. Most can be kept in a community tank with other fish. The black may be caused by high ammonia levels. Submit a water sample for testing or use a liquid home test kit to check chemistry. Ammonia can kill fish if levels are high enough. Partial water changes can be done daily to stabilize chemistry and maintain water quality. Use only aged or conditioned water that is temperature matched to prevent further stress or shock. My preferences for water conditioners include AmQuel Plus, NovAqua and StressCoat.

I have a 65 litre aquarium tank with 8 small tiger barbs fish ,6 Red eye tetra fish, 2 big golden molly, 2 rainbow sharks.........so can I add Discus Fish with these tank mates ? If yes ...if no ....so which tank mates is suitable for discus fish ? I
Thanks for your questions about your tank. You have a number of fish in your tank already - a general rule of thumb is 2.5 square centimeters of fish per 3.8 liters. Depending on how large your fish are, you may be close to the carrying capacity of your tank, and you will also need to plan on how the fish in your tank will grow over time (mostly the rainbow sharks). If you are looking for tank mates for discus, it is best to look for fish that are housed in the same temperature zone, and occupy different areas in the water column than they do. Examples would be bottom feeders like cory catfish, those that live on the sides and bottom such as plecos, and those that are in the middle of the water column like some species of tetras. For the question about vacation - I would not recommend leaving your tank for that long without someone checking on it regularly. Power outages can be detrimental for tanks, and water changes or additions would likely be required. Also, automatic feeders als
