Local society plant contest
I am in charge of organizing a plant contest for a local aquarium society.
A plant is chosen, and those who would like to participate obtain the plant, and then take before and after pictures. There are any number of different categories for prizes, ie most growth, most growth low tech, best aquascape using plant, etc. But mostly, the contest is just to increase awareness of planted tanks and discussion of same.
Last year, a crypt was selected (C. pontederiifolia). I was wondering if other folks had input into what types of plants worked well in the past for such a venture. Obviously, if we are going to follow the plants for a few months, stems are mostly out.
The plants I had considered are:
1) Anubias. Perhaps something unusual, other than barteri var nana.
2) Some variant of java fern.
3) An apono, although some get very large.
5) Bolbitis would probably get too large over time for most hobbyists.
Any thoughts, especially by those with experience in organizing such a contest, would be greatly appreciated. Thanks!
