Relatively new to fish keeping here. Our fish seem to be doing pretty well.
3 strawberry tetras, 3 blueberry tetra, 2 pairs of guppies, and 3 red velvent swords. (Headed for maybe 20 to 25 total fish for this tank).
Undergravel filter - reverse flow Aqua Clear 50 powerhead
Power Filter - Emperor 2800
In reading the sticky information for new fish owners, I see recommendations for water changes at least once a week and maybe more. I was coming into this thinking water change of about 1/3 to 1/2 max every 2-3 weeks via syphon/gravel cleaner.
I would then change the powerfilter cartridge about a week later to minimize total shock on the tank.
So, how often should I be doing water changes? with or without gravel vacuuming?
One last thing... one of my female guppies just disappeared. Any clue as to who the culprit may be? It's strange as we've all been watching the fish quite a bit an no signs that she was sick and no signs that any fish were being harassed. Our lone baby guppy vanished at the same time.
