TomO Posted July 18, 2022 Share Posted July 18, 2022 I recently collected a few of these from the shoreline of a northern Wisconsin lake. Sandy substrate, full sun, clear water. The “leaves “ are stiff like a toothbrush. 1 1 Link to comment Share on other sites More sharing options...
Fish Folk Posted July 18, 2022 Share Posted July 18, 2022 Maybe . . . Quillwort (Isoetes lacustris) 1 Link to comment Share on other sites More sharing options...
TomO Posted July 18, 2022 Author Share Posted July 18, 2022 Thanks, I hope it takes off with root tabs. I also found a val that was red, but during the disinfection process turned green. We hats lot of iron mines up here, maybe I should try some easy iron? Link to comment Share on other sites More sharing options...
TomO Posted July 18, 2022 Author Share Posted July 18, 2022 I found something similar but grows better with cO2.

gjcarew Posted July 20, 2022 Share Posted July 20, 2022 Looks to be some sort of isoetes. They're a unique genus and can be tough to propagate (depending on the species). Here's a report from my club's horticulture awards program: Gallons: 22 Long Temperature: 75 pH: 6.3 Hardness: 1 KH 3 GH SubstrateType: ADA Amazonia II SubstrateDepth: 1-2 Inches CO2Type: Pressurized w/inline diffuser Filtration: Oase Biomaster Thermo Canister SunlightHours: 4 SunlightDirect: Direct LightingType: LED Watts: 75 Watts LED (not on 100% though) ColorTemp: Chihiros WRGB FertType: Dry fertilizers FertBrand: generic FertDosage: 14 ppm NO3, 6.5 ppm PO4, 32 ppm K, .3 ppm Fe, 2.6 ppm Mg OtherInfo Isoetes japonica is a quillwort, and they reproduce unlike any other aquarium plants I know of. They do not do well with vegetative propagation (division). To propagate, I took a microphyll that was dying back off the outside of the plant. I then plucked another microphyll from the inside of the plant. As heterosporous plants, fertile Isoetes sporophytes produce megaspores and microspores, which develop in the megasporangia and microsporangia. The megaspores are located in the outer microphylls and the microspores are located in the inner microphylls, so it's important to take them from the two different locations. In good condition, the microspores and megaspores will form microgametophytes and megagametophytes, which then make sperm and egg, respectively. The megagametophytes are actually visible if you crush the base of a microphyll between your fingers. All I did was crush the bulbous bases of the two microphylls between my fingers to introduce sperm to egg, then scrape my fingers off in the aquarium substrate. A couple months later, a young isoetes plant popped up! In the picture, the young isoetes is located behind the bucephalandra. 1 Link to comment Share on other sites More sharing options...
jamieterrin Posted July 21, 2022 Share Posted July 21, 2022 Maybe Blyxa japonica or Eriocaulon Link to comment Share on other sites More sharing options...
