I used to have 5 Tropical fish tanks but had to sell them all 7 years ago, am now ready to have a new tank but am having trouble deciding what I want. I do not have a lot of space as the new house we have just moved into is very small. I first thought i would only have a small 2ft tank with tiny busy fish but my love is really for Angel Fish which I had some lovely ones before. Obviously I need a bigger tank, what size tank would you say I need for 4 or 6 Angels?
Also I would like an external filter this time as all my previous ones were internal filters, what can you advise me on this? i am told the Tetra Tec series are very good .
