Hello friends. This is the first forum I have ever entered so please go gentle on me if I get it wrong at first. I have two tanks. One 100 L that contains small fish and a new, 160 L set up for my angle fish who became a bit of a problem for her old tank mates. This has opened up some new possibilities for my 100 L tank and I am in the process of creating a rainbow fish display. Iv'e been reading the advice from members and have found it very helpful. Glad to now be a member and contribute myself.
