Bad news for Banggai Cardinalfish

[i have crabs]

ive managed to raise 2 batches so far even though ive only ended up with a couple left each time,mostly a problem with the setups i was using.all i did to raise them is feed them freshly hatched brine 3-5 times a day then i started mixing in frozen baby brine and when they where big enough misis.
another problem is they have to be between 6 months and a year old before they are big enough to sell.
i have 1 from the last batch in my biocube and hes 17-18 months old and barly bigger than some i see for sale in stores.
good news is my male has eggs right now so in another 3-4 weeks ill be doing it all over again if all goes well.
last time i tried to move him to another tank he spit the half developed eggs out and only 2 ended up living, so im gonna be real carefull this time and not freak him out.
