As for length to age i couldnt tell you but i would think that diet has a huge role in this, im also curious though because my del is just at 5 inchs and i want to have a rough idea of how long till he's a big boy. As for lifespan im pretty sure its quite long, i think i read somewhere that some one had one that was 38 years old? Im probaly over shooting that guess but maybe, check the sticky at the top of this section, it has Primer 3.0 in the title it will probally tell you and if it doesnt maybe beblondie would know, i beleave she is the most knowledgable about bichirs on this forum could be wrong though! =P
