Wow, thank you for sharing this! You have such a very unique hobby, in my opinion. I haven't met someone who is very passionate about fishes and aquariums! I'm sure you've also discovered a lot about them ever since you started.
Just curious, but how frequent to do you clean the aquariums? Doesn't it become a hassle?
I seldom clean the tanks. Im just using a very good quality filter. Just cleaning the filter once a month, and adding water to the tanks if needed.
