Looking back, here is a list of tips that I wish I had known when we set out on our apartment hunting journey. Hit the ground running. While the internet is an easy way to search for housing on your own time, the internet is not always the most up to date way to find a rental flat in London. To get the best selection, you have to hit the ground running and set about looking at every real estate office window to see what they have to offer.
Place the fish in a bowl or bag filled with the quarantine tank water. Let the bag or bowl sit on the surface of the main tank water for 15-20 minutes. Then, use a clean cup to scoop some of the main tank water into the bag or bowl. There should be 50% main tank water and 50% quarantine tank water in the bag.
First, you need to cycle the tank before adding fish. If you just fill it up with water, and put them in, they will die. Cycling takes anywhere from 2 weeks to over a month. Once you've cycled your tank and are ready to add the fish, don't just bring them home and throw them in. They should come in bags. Sit those bags with the fish in them in the tank water for about 30 minutes so they slowly get used to the new temperature. Then it will be safe to put them in.
