It may be a stupid question, but do bee shrimps need a male to have their eggs fertilized, I had a bee which berried last month and gave birth to 6 shrimplets, now they are about 5 mm is size, just today I see it berried with over 20 eggs, the only problem is the mother bee is they only adult in the tank with two blue Bolts at 12 mm, also I do not know whether the Blue Bolts are male or female. All the others shrimps have been removed.

What Simon said. If there are no other males apart from the Blue Bolts, then these offspring will be Michlings. I can see the need for yet another tank coming up

Ok so i didn't manage to get to B&Q (the hardware store) because of well life, however i did manage to get waterproof silicone bathroom sealant that is non toxic from a supermarket, they were £7 per bottle, but i checked their website and a bottle from them would cost £4.97. i have not however been able to make the Drip Acclimator Mk3 as i am waiting for the flow regulator i got from Amazon as they are apparently coming from China. This could however as noted before be optional and i could close the pipe down with a lighter to make work, i'll do this when i have the time. so i left the tank until yesterday when i checked TDS and it had gone up to 320 so i did 2No 10% - 15% water changes at 0TDS as recommended over the last couple of days using the specifically made Dripper set to 2 - 3 drips per second. i have now checked my water perimeters and they are as follows:- PH - 7 dKH - 4 dGH - 8 Temperature - 22C TDS - 281 NH4 - Unreadable N02 - Unreadable N03 - 15PPM P04 - 0.5PPM As i see it i can leave the tank a couple of days even with this level of Nitrate because its still below the threshold i have set, so come Wednesday or Thursday I'll know what to do. I will then do my next water change at 200TDS. My coverage of Duckweed isnt spreading as quick as it has previously so that is telling me my tank is maturing and i can start to remove it, although I'm going to keep a bit for the set up of the next tank. Although i haven't seen any dead shrimp im still only seeing 3 - 5 adult shrimp at any one time. Note i said adult, because i checked today and i noticed tiny 2mm - 3mm shrimp, see photo attached. The berried shrimp must be hiding in the plants. I have only counted 2 baby's at 1 time but my theory is id have a couple of dozen right? my girlfriend is elated with this news as she is now determined i don't need to buy more.

As far as I am aware they need a male. It is exciting to have new shrimplets! One of the blue bolts may be a male I suppose and mated if it is old enough? Great picture. I would guess they still produce eggs even if there is no male in the tank but assume those eggs just will get dropped? Hopefully someone with greater knowledge will let you know! Simon
