Thanks to all of you for this very useful information. The link for article is really very informative. I have kept 8 small and 2 big angels in my community tank whose detail is as follows:
Size: 72"x12"x18"
Fish: 10 angels, 5 dollars, 2 plecos, 2 tiger sharks and one dwarf stripped catfish.
Decor: artificial plants, real big pebbles, white and brown gravel as substrate.
Filtration: UG filtration with
powerhead on it for internal and
canister filter for external filtration
Heating: 300 watt ehim fully submercible heater with 45 degree angle and set for 25 degree celcius temprature.
For breeding I am setting another tank with dimentions: 24"x12"x18".
I am very much confused about peat and peat moss. will you explain what exactly peat is? and from where I can get it. I am uploading my tanks pictures. These are taken before putting angels in it. Soon I will upload the fresh pictures with my angels and also provide my tanks video link for youtube.
Thanks once again for your valuable co-operation.
