I have heard people say they feed theirs cucumbers can any one tell me what the benefit of that is and if the fish like it... My babies will eat anything! it's funny though, the bigger (year old-4-6 inchers) are getting picky they don't like the spirilina anymore, it does seem this has happened ever since I started giving them blood worms as a treat twice a week they LOVE them. I would not give them any beefheart though I did try that once and they didn/t like it anyways... They also dont like the 3mm NLS even the big 6 in fish seem to prefer the 1 mm. I havn't seen any 2mm for sale I will have to look online for that! Good luck with them they are very hardy fish to keep I have found!
