Choosing the right type of aquarium
Have you the got happy fish?
Many times people buy a new fish tank then purchase new fish without any thought to the demeanor of the fish they bought. My first tank was a disaster! I bought some of these African Cichlids because they were very colorful. I then bought some Angelfish. Well without knowing it, I was basically feeding my African Cichlids fresh Angelfish! Make sure before you buy fish you check the demeanor of the fish you are buying. Another thing to consider is the growth of the species you are buying.
You could end up feeding your guppies to a large mouth Bass!
