I have 8 convicts in a 50 with alot of caves,a pair spawned after about 1 month. i was so excited i thought about taking the fry out but decided not to ( i had tried this with rosey barbs and all the fry died:water must not have been the same) they were fine for 2 wks then i woke up yesterday to find all of the others attacking the parents ,to get at the fry. now there gone the parents are mangled and im mad because i didnt do something right after the fry hatched.i tried to get them yesterdaybut they kept going back in the caves. now i have another pair (same male) that hatched this morning in a cave that is under gravel with a hole just big enough for the parents to get thru. did they kill the others to make room for these or should i just take a chance and vacum these fry up and put them in a 20?
