Ive had my hisser colony for about 2 years now and they are in a large RUB with vents
85 F and they breed well, however ive noticed since i had the original few i started with 2 years ago, most of the roaches end up as smaller adults
the past few months, especially the males, the females still grow to a good size.
Also im finding quite a few dead each day (while the main colony seem very healthy, they are not overcrowded) and the dead can be of varying age.
They dont hiss that much but i guess thats because they are seen every day.
Any thoughts on the above please.
Also am i right in saying the protein they need doesnt have to be animal based ?
