Tank Conditions & Fertilisation
I bought a small clumps of Mini Pellia from Malaysia back in Jan 2007. It seems that the scientific name of this plant ID is Riccardia chamedryfolia, as suggested by Xema and rain-, thank you both! Unfortunately, 90% of the plant died during postage (1 week journey). But I tied the remaining 10% of fragments onto two pieces of stones in the hope that they will survive. Luckly they survived! However, they are so slow growing that, after nearly 5 months, they are finally large enough for me to take some photographs for this ‘mini’ article! They are grown in my 8L Tiger shrimp tank with 11W compact fluorescence light and CO2 supply (DIY yeast culture). Water pH is about 7, KH ~7.8 and GH ~16 (typical London tap water) and temperature about 22-24C. I dose the tank every other day with very small doses of Seachem Excel, Fluorish, Iron, Potassium and Trace. I prepare a 500ml bottle of Seachem mix for the ease of dosing. Below are some photos showing the growth stages from the begining (Jan 2007) until now (22 May 2007).

I tied the small amount of Mini Pellia down onto small pieces of flat stones as shown above. I found some Najas indica in a freshwater lake in Ipoh, Malaysia.

After 4 months. Note it was attacked by some kind of hair algae. To get rid of the algae, I removed the them with a pair of tweezers, increased Seachem Excel dosing and CO2, which seems to work.

This photo (and below) were taken on 21 May 2007, ie, after almost 5 months of growth! For scale, I have placed some Süsswassertang (which look similar to Monosolenium tenerum) next to the two clumps of Mini Pellia in the foreground. Tiger shrimp is about 2cm.

Close-up shot showing the difference in size between the Süsswassertang (which look similar to Monosolenium tenerum) and the Mini Pellia in the foreground. The Tiger shrimp is about 1cm long.

Close-up on frond structure shows the branching pattern without the presence of  veins along each frond.

A small fragment on my index finger.

The same fragment as above trans-illuminated against the aquarium light bulb. Note the absent of veins within the fronds.
