Hi, I would say the 30cm cube is perhaps a bit small for them, they are not very active in this tank, mainly hiding at the back in the java fern and occasionally swimming out the front looking for something to eat, not sure on the male / female ratio and no idea how many i still have, I do see spawning activity but not sure if they have bred successfully, never really seen any fry, I started with 10 small CPDs and at a guess still have about that many, could have probably lost some (never found dead fish), maybe they bred occasionally... I cant say if any have really bred, probably not, I think they would eat their own eggs, also the corys would eat the eggs if the found them.
They do chase each other occasionally but nothing any different from what I see fish do in bigger tanks
Yes still have a heap of Cherry shrimp in this tank, im sure some of the smaller shrimplets get picked off by the fish but overall the population is stable with some small juvies that survive and grow large enough to not get eaten
I have exactly same sized tank with 8 CPDs, betta and some random shrimps. I think boraras brigittae would be a better choice, but now that I have those CPDs I'll probably stick to them. I have 2 females and 6 males, they're breeding regularly, but the eggs are eaten. They were in the tank without a betta before and I never saw them, always hiding. Surprisingly betta works like a leader for them. Now they're swimming in the open space most of the time. Adult shrimps aren't bullied, but the slow growth of the colony suggests that most of the shrimp fry is eaten.
