Hi all! I am new in the aquarium world. I have been struggling the past few weeks to keep some fish alive and I really need some help. I originally purchased a 3 gallon tank for 1 tiger barb and 3 neon tetras. I now have 1 tetra remaining. Once they died I realized I completely over crowded them and it's possible the water was not prepared enough.
Fast forward to today.... I am wanting the same types of fish and I am wondering if a 10 gallon will be enough? Can I prepare a 10 gallon with the appropriate sized heater/ filter with water conditioner and water balance for these 4 fish? Do I need a larger tank or more fish(since I know they're schooling)? How long do I need to cycle before adding fish? How much water do you remove when doing tank cleanings, and how often should you clean?
Any other tips for what i may be doing wrong is appreciated. Super bummed these 3 passed
