Community Tank

After having stopped keeping aquarium fishes for quite a number of years, I am back now with a new community tank, 2′ in size and powered by two external hanging filter filtering water at 100 gallons per hour. Fishes include Guppy, Tetra, Sword Tails, Red Eye and some other funny looking fishes. Water is crystal clear with two filter running. Total number of fishes is about 30.

Hazy Day

The Haze across the KL skyline is extremely serious today and the visibility even during noon is extremely poor.

Vortex Filter for Koi Pond
