This tank's substrate is 3 years old ADA aquasoil. The white "sand" in the picture is actually ADAMan that stuff looks awesome!
Looks like you're growing it in regular gravel?? Does it not need special care?
Don't need to worry too much. I think your belems are just trying to accommodate to their new home. The old leaves of Toninas might melt a little bit when they change environment. I think belems can do well in both high and low lights. However, unlike Belem, Uaupes seldom grows taller than 2". Therefore, I believe they don't need much light in nature. Nonetheless, it's still possible to grow Uaupes in high light but the margin of errors will be narrow because they will melt much faster in high lightreally, it was my impression that most toninas require very high light would you say moderate light is favored for belem too? I just got some super healthy belem from a friend (tom barr) and its starting to look raggy in my tank for unkown reasons. I have about 5.5 wpg CFL, adequate pressurized co2, heavy EI ferts, ADA aquasoil, kh around 2, very good flow/ filtration and it still isn't looking good. any help would be appreciated
