Not having [SIZE=10.5pt]available[/SIZE] tanks/ space can be a problem . I have a large number of tanks so can obtain many fish. halfbeaks are best kept in a species tank only. I like to grow the fry on in separate tanks.
[SIZE=10.5pt]We get a few types of halfbeaks[/SIZE] in the uk any one buying Dermogenys pusilla from L.f.s should be aware that some can be of poor quality.
