cheers james they are so small that 1 extra large prawn , cut up small feeds them both ....... twice!!
cheers ian . altho tbh i wasnt overly happy with how these shots came out , i havent got much light in the tank , just a single 38w tube. so i had to open the aperture right up on the lens and slow the shutter speed down . but ive sorted that out today tho by ordering 2 more tubes which i will hook up to my spare double light unit . that will give me much more light for photos which means il be able to set the camera up more geared towards just taking good shots instead of getting over a lack of light.
