Hi Tony. Nice to know you're one who goes for rare & exotic plants. Must be real costly to buy 'em in the states huh. I'm keepin' Tonina sp., Tonia fluviatilis. Eriocaulonceae sp., Ludwigia sp. ( looks like E. stellata ) and a few other rare ones. Tonina specimens are very demanding plants. Few pointers to share with you,
1) They need plenty of CO2, light & fertilization.
2) Thumb of rule for CO2, at least 3 bubble / sec for a 3 ft tank.
3) Lights. I use a mixture of tri-phosphor FL tubes and PLs. 6500K & 10000K
respectively. Thumb of rule, 3-4 FL/ PL tubes for a 2 - 3 ft tank. More
if your tank is bigger.
4) Fertilization. Abundant base fertilizer and regular dosage of iron & trace
elements.
5) Also, watch your water parameters. Tonina originate from the soft
waters of S. America. Mostly in cristalinos & blackwaters. Thumb of rule,
kH 0-2 dH, gH - not exceeding 10 dH, pH 6.0 - 6.8.
Hope you'll find them useful. []
