Yep i have watched that video. Mark is really passionate about the hobby, you can hear it in the way he talks about things. Much like yourself and jayc. Thanks for sharing this video, it is indeed very relative and actually it did encourage me a whole lot. 14mins into the video he covered mummy shrimp molting with the eggs.(forced molt) 20plusmins into the video he covered failed molting, (post molt or stuck in the molt, aka "white band of death mr diamond") I learnt alot from this video. My thoughts: I think i myself killed yellow mummy shrimp, not the water parameters, i did it. Realized i should not have done that 800mls water change after they were in there. There wasn't a need to do that water change actually. They had just acclimatized to the tank not too long ago and i should have left them to it. (Prompted by mark, he mentioned when there are berried shrimps you minimize water changes) I had the idea that i wanted the water to be pristine and so a small 800mls water change isnt going to be shocking anyone. I failed to remember that they had just came into this tank from the breeders. So had i not done the water change, they would not die. I think the drip acclimating done for them in the bag was done well but i shocked them further, another time you could say, when i did that water change way too soon. Kills me to remember that actually that water change was not really needed. (Believed nitrates was low, tds was just about climbing but not rocket high). Could be why after that, they dropped like flies and than the one baby shrimp from the pail died along as well. Than at this point in the video i was reminded of my main tank with the crystals n reds. When all the females were berried, i hardly did water changes. Actually only once or twice and very small amounts and the babies were all successfully hatched with the mummies not dying till much later. This is a lesson for me. Over caring for the tank is gonna harm them more than anything(fussing too much) He also mentioned failed molts in shrimps and had related it to diet. (After he dropped the broccoli into the tank) Makes me think, i actually neglect the shrimps diet generally. In the sense i do not feed them regular enough. Had thought they can eat all that biofilm in the tank, i only drop a minute sized pellet or powdered shirakura chi ebi in for them once a week or sometimes even once every 2 weeks, i wonder if this could be why they seem to be dying from molt failures despite the water being relatively better than last time? Noticed that they die usually with a gap after their heads and always after a water change. Because the water is really better than before when i first started and i slow drip back new water into the tank but it is so frustrating to see 1 die day after a water change. I may have neglected their diet in this aspect??? Will give a try to use fresh boiled foods for a change to see if things improve, want them to have more vitality for sure. Im sure if i neglect this area it would affect breeding for sure, i had been too obessed with getting the water better till i neglected nutrition. Lastly he talked about keeping everything to a constant and in a way he is saying dont chase numbers, see what works for you in your setup and that takes trial and error. Will definately keep that in mind now that i am better than when i first started. I think this video was really meant for me, thank you again simon. Sent from my SM-N950F using Tapatalk
