I have a couple of plants in my recently planted 100 gallon tank that I do not know the identity of, any ideas? :? Both of these plants have been in the tank for around 3 weeks the top appears to be doing ok and the bottom one is growing very quickly. Both plants was rooted from a cutting but I have noticed what appear to be more roots appearing at various points along the stems of the top one, is this normal? The bottom plant has lots of thin hairy fronds sprouting all over it, is this normal? Some water info: PH: 7.4 DKH: 5 GH: 14 Temp: 26.5 Nitrite:0 Nitrate: 50 Ammonia:0 Phosphate: 0.25 All advice much appreciated.
