I bought one of the first biorb 30s about 12-13 years ago. I had 3 fancy goldfish at the time aged 4-5years and all three loved the tank. They lived in there for a further 10-11 years. I did water changes every week and changed the filter every 2-3 weeks and they were very healthy and happy. This isn't a tank if you don't want to do any maintenance or water changes, it definitely doesn't clean itself. I have now converted it to tropical and have four platies, they're much cleaner than the goldfish. Took about 8weeks to cycle the tank and now I do a 15% water change every Friday and change the filter probably every 2-3 months. Very attractive tank, happy fish if you make the effort to actively maintain it.
