Ok. So as of today my 16 gallon bow front tank makes a month. I have 7 panda corys, 3 serpae tetra, and 2 sunset playys. A heater, bubble wand, and a bio wheel filter.
Here are my few clean up questions: (If you cannot answer them because you have something bigger than a 16 gallon tank then just make an estimated guess
)
Q1: I do a 10% water change & gravel vacumm every two weeks. Is this good?
Q2: When should I replace the blue filter pad (The blue pad that is inside the filter box)?
Q3: When should I replace the bio wheel (The wheel that spins when the water shoots out the filter)?
Q4: When should I clean the decorations I have in the tank? I have 4 fake plants, a Castle, and Wizard I like to call Gandalf.
Q5: When I do clean these decorations, do I do them all together or like one every week?
Ok now for my Wondering question........"DRUM ROLL"
Q6: I was thinking, what do fish eat when they are in the rivers, oceans, lakes, streams? Its not like God drops down fish flake food? I was just wondering. What would my Tetras eat if they were in the wild? lol silly question i know...but i was wondering
