I have a pair of Hoplosternum Thoracatum, reared from a group of youngsters, that have been in condition for about 6 weeks now. Males pecs fiery red, female the shape of a little fat cigar (bless her). Problem is, still no eggs! They get frozen bloodworm, mysis shrimp,chopped mussel and prawn PLUS pellet and wafers. Do you think they're, well, a little shy?
