You are welcome, Kevin.
I have learned many a thing with keeping wild fish. If you bring it into your tank FROM the wild, you will have it in your tank FROM the wild. You cannot boil your fish to destroy the algae, but you CAN boil the stones and other non-organic, non-living things you put in the tank .
I had a real problem with cyanobacteria and long hair algae for months. I added crays, turned down my lights and reduced feeding and it went away. The crays "mowed" the grass and I have zero hair algae left. Since I reduced feedings, that hard-to-remove algae on the glass has gone away.
They are in no hurry to go anywhere. However, they CAN outsmart a rabbit! Haven't had much luck with mystery / trapdoor snails, but the river snails have done well. I do believe that the trapdoor snails typically need a mate but can change to hermaphrodite depending upon conditions. My single large river snail I am lucky to see once a week, but there was babies all over the place! I also believe that my female rainbow darter is snacking upon them. They were all over the place (15-20) and now there's like 5.
I am tired, grumpy, frustrated, and worried for my kids and getting them into my custody. However.... I LOVE fish, snails and everything to do with legally collecting and keeping them from the wild. One balances out the other, and even more so because my kids DO like my native fish! My daughter helped me collect the fish for my 29 gallon. I want to feel (and do it) that way again.
God bless and safe and legal collecting!
The Grumpy Old Man.
