Hello Fishlore community! I am a beginner at having an aquarium set up and had a few questions for all members. I have been frequenting the forum for a while and it has been helping me set up this tank and felt that I had to make an account to continue this experience. All input is welcome and I appreciate everybody who takes their time to give me a helping hand. I will begin with my set up and can take pictures if necessary if it helps. As of right now I have -A 10 gallon tank -A heater set at 76 degrees Fahrenheit -An Aqueon filter set for a 10 to 20 gallon tank that cycles water at 100 gallons per hour -A neon light fixture along with the top for the tank -A PH of 7.2 -0 nitrites -acceptable ammonia i believe its 0 or around that range -the tank is cycled to the best of my knowledge and from what I've read here and everywhere else about the nitrogen cycle (been going on for about a month now before i have added fish) I did take samples of the water to a local Pet Co. and had the water tested. -The hardness is relatively soft - I have 2 plastic plant fixtures in the water - I have 1 rock formation in the water - This is a fresh water tank My community: 3 Neon Tetras 2 Black mollies 1 Catfish that I can't remember the name of for the life of me As far as I know my tank holds 8 gallons of water and the fish sizes for when they are grown should be acceptable for the amount of water I have in the tank. Now for my questions, and any answers would help me a ton and are welcome. 1. Do I need an air pump? 2. How often should I clean Gravel? 3. I have tropical fish flakes and freeze dried food as well, how often should I feed the fish, and what quantity should i feed them? 4. I heard that neon tetras like to school, should I purchase 2 more? and would that be acceptable for the amount of water i currently have? 5. should I purchase more hiding spots for my fish? the aquarium set up right now seems pretty laid back and the fish seem generally happy. 6. what is the correct temperature for these fish? I have read from 74 to 82 degrees, is this true? 7. Will the mollies grow larger than I was told? right now they are about 1.25 inches and was told they wont grow much larger. The tetras are all about .5 inches and the catfish is about an inch, giving me a total of about 5-6 inches of fish for the 8 gallons of water I have after I have accounted for water displacement via the plants and the stone. I have thought about these questions but if anybody finds any problem with the tank or the fish I currently have in it feel free to let me know, It is all about the fish after all. I can provide pictures if necessary, and again, all comments are welcome. Thank you all for your time.
