I have 30 tanks in a very small fishroom. The room is space-heated to a temp of 28C so no heaters needed in the aquariums. I have been keeping tropical fish for 60+ years and originaly kept my breeding records in a note book. However, these notes had a tendency to get lost or mislaid as the years went by! With new technology it has become much easier to make short videos of the breeding and raising of the fish and these effectively have replaced my written breeding records. This is the basis of the videos on this channel - no 'Hi Guys' or 'What's Up' - they are just my breeding records.
Originally I did not make the videos public but kept the content of my channel private but in recent years I decided to make them public. If you find the videos useful/informative please give them a like and share them with fellow hobbyists.
