I had another silly old woman moment yesterday - well Sunday but I noticed yesterday! I am getting some new shrimp so needed to clean out a tank for them. I caught all the shrimp and hunted down the babies . My shrimp must know when I'm going to catch them because they always have their babies the night before!!! Anyway I took everything out of the tank except substrate and most of the water, gave the substrate a big stir and pooped 2 power filters into the tank. Once that was clear I topped up the substrate with a thin layer of new substrate and put the power filter back on - everything going to plan so far. Next I went to my RO reserve which I keep outside under a verandah. We have had very hot weather in Adelaide for weeks so the water was about 30 c . I put 20 litres of straight RO into the tank at 30 because it was empty of shrimp - are you still with me? Then I needed to up the TDS as the new shrimp are kept in a much higher TDS than mine. I usually add the Salty Shrimp in the bucket and mix it well before adding to the tank but I needed to adjust the whole tank so added it to the tank. So so far , I've swirled the substrate = probable ammonia spike, added warm water, added straight RO water, added straight Salty Shrimp = would or should equal dead shrimp if there were any in there - but I had caught them all hadn't I? Once that had settled and the filters cleaned I was happy enough to add the plants and rocks back into the tank . THEN yesterday giving the tank a final water test and checking that the tank was ready for the shrimp that were arriving the next day -today - I noticed colour and movement swimming on the substrate and sure enough there were tiny tiny baby shrimp in the tank. I doubt they were in the moss as I had that in a separate container and had given it a good clean and checked the water the Moss had been in finding nothing. I don't think they were in the sponge filters because I had taken them out several times to give them a good rinse in the old tank water so they must have been on the substrate . Luckily I had been very gentle putting that in as I didn't want to stir up the dirt from the new substrate. So yesterday I caught out about 20 babies and this morning another 10 , there may well be more but I don't want to move the rocks this close to the new shrimp arriving. I will just have to try and catch them as they grow so I don't mix them up with the new shrimp. I breed them tough!
