I admit, I have lesser time to take care of my fish. There's a day that I'm unable to check on them. No worries, they are alive and kicking. I have no worries too because their aquarium doesn't need to be cleaned everyday. In fact, they thrive on how it looks now.
There are algae developing in them, which serves as their food. I learned a lot from my brother who's business is selling and breeding different kinds of pet fishes.
Look at the aquarium, they're very much alive. In fact they looked so happy. They even multiplied, and gave some to my friends!
