I use to frequent this site, but have been absent the past few months. I have a few new questions.
Over the summer I got pretty neglectful with my bettas. I was use to do bi weekly 30% water changes, but I started only doing like 90% changes once a month.
But now that schools back in, I'm getting back to the old schedule. I'm planning on completely breaking down and cleaning out my tanks this weekend...
1. If neither of my fish seem ill is it okay to use the same cups to scoop water out? If I rinse it?
2. Whenever I feed my female it takes her several tries to get the pellet. She misses it. Is this a sight problem?
3. What is the best way to completely clean out gravel?
