Tiny Tank, not so Puffer Hello. I have a 4.4gal UK fishtank, which measures 42x22xh33cm. According to the standard rules for fish per fishtank, it should be big enough for a Congo Puffer (Tetraodon miurus). However, I read something about this puffer somewhere that it needs a tank at least a 50 gallon tank. If it was in my 4.4 gallon tank by itself, would this be enough space for it? Thanks Tim Jeffree <Glad to see you're investigating before buying... and yes to the present system being too tiny... even starting with a tiny specimen, it would be too "psychologically" crowded. There are some other small freshwater fish choices that would go here: the littler Danios, rasboras... perhaps a couple of small Gouramis... some plant material... Some coverage of these can be found on our site: www.WetWebMedia.com for your perusal. Cheers. Bob Fenner>
