60-P high tech, 45-P low tech
I first joined plantedtank in order to post about seed shrimp in my 45p with no luck getting a response. Here we go again! A year after my first experience with a seed shrimp explosion in my 45p, the only solution I found was getting a dwarf gourami to nip the problem in the butt, and it certainly did the trick! This December, I set up a new 60p, everything invitro like last time (except for the trident java fern which I sterilized), new filter, new media, new hardscape. And the little guys popped up again! I'm convinced they are in my tap water or something, and I think my harder water makes them even happier molting. I feed very lightly, 5 times a week and do maintenance every weekend. With my experience in the 45p they are amazing algae eaters, but they don't seem to die down unless there is something actively eating them. In my 60p, I have a hand full of neocaridina shrimp, a shoal of ember tetras and 5 otos. I don't want the seed shrimp to outcompete the otos or shrimp for food (which happened in the 45p). Are there any nano fish designed to eat hard shell inverts like these? The gourami loves to hunt for them all day long, but tetra never seemed interested. In the 60p I'm trying to keep only nano fish or close to it and am looking to introduce more to help remedy the problem. I read CPD's or boraras would eat them. Is it more their nature to eat them much like what I experience with the gourami? Here's a photo of the tank (plants still growing in), and a video I took with a magnifier glass up to my phone's lens to show that they are in fact seed shrimp / ostracod, not daphnia. Any advice would be much appreciated!
