The smaller black one looks like the lfs version of the Kellogi. If so, they are actually pen raised and live pretty good for about 2 to 3 months. Then like lightning, they start to form discolorations spots and do a crazy wiggle and swim off. They continue to eat and then just crash over night. One I had purchased did great for 2 months, fed them and actually watched him eat about 5 mysis and 1 hour later was dead. I was going the cheap SH route and getting them for 20 to 30 bucks. Now I get the captive breed from local people and mine are doing great. I have Erectus and hope to have some fry in the next few weeks.
Good luck
