C Savidge Posted September 15, 2020 Share Posted September 15, 2020 Hey everybody, I'm joining to learn more about things like colony breeding, growing fish in greenhouses, and keeping native species. My main tank is a 125g with apistos, platies, and cherry shrimp. I'm looking forward to the conversations. C Link to comment Share on other sites More sharing options...
Taylor Blake Posted September 16, 2020 Share Posted September 16, 2020 @C Savidgewelcome lovely tanks. what kind of natives do you keep? I have a 300 with some US natives Link to comment Share on other sites More sharing options...
C Savidge Posted September 16, 2020 Author Share Posted September 16, 2020 Thanks Taylor, I dont have any natives at the moment but I would like to try setting up a bio-tope tank next to one of the cold mountain creeks, and pipe water through it from the creek. I like all those little mountain fish like sculpin and darters. Link to comment Share on other sites More sharing options...

Taylor Blake Posted September 17, 2020 Share Posted September 17, 2020 This is my 300 gallon hill stream tank I'm working on adding more natives but on my list is war paints and some more darters. I'm in Minnesota so I'm a little limited as to what species I can obtain myself. This is a neat map I found of US freshwater fish diversity. I don't remember the source of the map however Link to comment Share on other sites More sharing options...
Daniel Posted September 17, 2020 Share Posted September 17, 2020 We live in fish paradise! These are the first 2 sentences of Michael Sandel's dissertation defense from 2011 "The southeastern United States is home to the greatest regional freshwater species diversity found outside the Tropics. Despite a long history of scientific investigation, the mechanisms responsible for generating and sustaining this diversity remain poorly understood." It is an awesome paper if not a bit nerdy. Here is the invitation to his presentation of his thesis to his defense committee. Although he focuses on Pygmy Sunfishes, he basically explains everything we know to date on why there is so much freshwater fish diversity in the Southeastern United States. I have a copy of the paper if anyone is interested. Link to comment Share on other sites More sharing options...
C Savidge Posted September 18, 2020 Author Share Posted September 18, 2020 Taylor Blake, I really like that tank. Do you collect all your natives yourself? Is there a cheat sheet for what species are legal to harvest? Daniel, I would like to look at that paper. I know the continental glaciers stopped north of here which allowed for uninterrupted development of life. Also no glaciers means no lakes, which means more extensive river systems for fast water specialists. //content.invisioncic.com/b300999/monthly_2020_09/image.png.f2a47d9755fcdc747f70279322073aee.png Link to comment Share on other sites More sharing options...
Taylor Blake Posted September 18, 2020 Share Posted September 18, 2020 @C Savidgeits all up to your local laws up here in MN the local aquarium club dose a darter collection every year and I have gotten my dace from local bait shops and the rest of the natives came from jonah's aquarium. Some states all you need is a fishing license others you need a special permit for aquarium fish collection and others you need a bait license Link to comment Share on other sites More sharing options...

Daniel Posted September 19, 2020 Share Posted September 19, 2020 The paper is fairly dense, but it was about my beloved little Pygmy Sunfishes so I slogged on through and here is my summary. In a nutshell as the glaciers grew they destroyed upper drainage aquatic habitats. But at the same time all that ice locked up a lot of water so river drainages advanced outward towards the receding seas (actually creating new distant river drainages). Sea levels dropped 375 feet lower than average. Refugias were created in the non glaciated areas in form of large alluvial tributaries with almost no drainage coming into these areas from the glaciated highlands. Imagine the coastal area of the eastern US extending out the continental shelf with marshy slow moving rivers interbraiding with each other. Genes and the fishes that carried the genes began the cross the now non existent river boundaries. Ranges expansion went wild. Dogs were getting married to cats. Okay, maybe not the last sentence. Species that had been separate before the ice age now came in contact with each other again. Eventually though the warm times would return. The ice caps would melt. The river and estuaries and bays became separate again as they reversed course and retreated in to the interior of the warming continent. New species would begin to develop now that they were isolated once more. And then after 80 or 100 thousand years it would all repeat again. Play that movie over and over again and you end up with a global hotspot of fish genetic diversity all right in our own backyards! 1 Link to comment Share on other sites More sharing options...

Apds Estes Posted September 20, 2020 Share Posted September 20, 2020 Hello, also from the Smoky Mountains. 😁 Very nice to meet you and glad to finally find someone near by. I have a tropical community tank (55) and a 30 gallon as a grow out for a common pleco waiting on his 75 to be ready (my sons) I am hoping to then turn into a puffer tank 1 Link to comment Share on other sites More sharing options...
