Hi,
It’s great to hear from your future attempts to breed paros!
Actually, it is quite a tricky question. You certainly don’t want to overfeed them but they need nutrients to build eggs and spawn.
I also want to mention the fact that the amount of food needed for Paros strongly depends on the size of the adult animals. I experienced this with my linkeis that have grown to a remarkable size and therefore also need a lot of food, compared to the much slimmer tweedieis.
I always practice about the same method which seems to work pretty well. I use a really small plastic spoon which is probably about the amount of 1/4 teaspoon or so of EGGS which I put into the hatching box. Since they don’t hatch all at once, I can easily find BBS for about three days. Usually, the second day is the strongest day by means of productivity. Since the BBS loose a lot of their nutritional values shortly after hatching, I feed them before I put them into the paros tank.
This procedure leads to a pretty efficient nutrition and also to a variation in the amounts of food I give them. Sometimes, when I’m too busy, there will also be a day of starvation but that’s no problem for the adults. I use this amount of food for every tank with Paros I have but in neither of them, there is only one pair so in your case, It would be less.
I would also like to mention that, especially while the paros are growing, they need more food than they would need when they are grown up.
I think, If you observe your animals a lot, you will get a feeling for the right amount…
I also would think over your tanks size again… 7 liters is not that much… If you want to extensively breed, you need a bigger tank with many hiding places for the fry to survive and If you want to breed intensively, you will need more larger Tanks since the offspring will stop growing if there is not enough space…
