kelseylynn Posted February 28, 2009 Report Share Posted February 28, 2009 Threadfin Rainbows are also a great option for small tanks. They don't get very large, and the males have long colorful fins. They look so cool when they're displaying to each other! Dario dario seem like very interesting little fish too, small and colorful. Sadly they're really hard to find (or at least I've never seen them in Calgary). Quote Link to comment Share on other sites More sharing options...
