For our 40th wedidng anniversary recently we were given a 50 liter tank, we filled it with water, heated it up to 23/24 degrees, added washed gravel, plants, and all the required additions to the water . Purchased 6 neon Tetras, 3 assorted platy, and 3 guppy (1 male 2 female) One of the platy keeps hiding in a corner and can stay very still for a long time, it is rather eary, but is it normal? Now we need to replace some of the water, so a bucket is standing ready but how do we get it up to the right temperature? How do we know when a fish is pregnant? Can we leave babyfish with the adults? So much to learn but so much fun as well.
