| They grow extra large in an aquarium but you have to watch out for mold. If they do go into a slump, simply cover them with a clear plastic container or baggie. The best thing is to not wait until they do go into a tailspin and cover ASAP. I placed a lettuce container from the grocery store over mine since I brought it indoors a few days ago instead of waiting a couple of months for the eventual decline. Here is an example of a cover over B. goegoensis.
