Starter chunk of bolbitis rhizone -- an obvious fern -- plus my foot.
Origin. Bolbitis
originally came from Africa (how’s that for non-specific?) where it seems to be
widespread. You’re not likely to find it in your local fish store, because:
·
Bolbitis is often not available,
·
Bolbitis is hard to display,
·
Bolbitis grows slowly, and
·
Bolbitis can be costly.
Usually
Unavailable. Retailers won’t find bolbitis
on very many price lists. Most wholesalers offer it only
sporadically, because most dealers have little idea how to grow or show
this good looking fern.
LA
If you stick your rhizome into your substrate, it will rot off like this.
Hard to
Display. Stick it in the gravel (green side up) and watch it
grow. nnng. Wrong answer. You’ll rot your
rhizome. You have to attach bolbitis (until it figures out how to
attach itself). This means you won’t see
your dealer tossing dozens of bolbitis in an aquarium like
anacharis. And wholesalers can’t ship
attached bolbitis starters because the shipping process pretty much
unattaches them.
LA
Once attached to wood, bolbitis grows nicely. Year-old specimen.
Grows
Slowly. I never did totally absorb that class on Polypodiopsida,
but I do know that ferns grow best when you plant them on the north side
of your house. They can’t handle full sun. It
“burns them out.” So I usually shade them with
duckweed. With slow growing bolbitis, high light grows algae very
rapidly. Algae is a highly competitive plant some see as a worse curse than burn
out. Putting bolbitis in low light situations causes them to grow
slowly. You could be looking at a one-year project to grow a nice
bolbitis. Or, in some cases, a two-year project.
LA
Bolbitis takes nearly forever to attach to hard rocks.
Not Cheap.
Starter plugs (if you can find them) are reasonably priced but
unimpressive. With all these problems built in, it’s
no wonder a nicely attached bolbitis specimen costs so much.
LA
Bolbitis firmly attached to the top of a clay flower pot.
Set
Aside Program. Since some of us resist forking out the bucks for
a carbon dioxide injector, we need to start our bolbitis plugs then set
them aside to grow for a while -- a very long while. A good water
flow seems to encourage them to grow faster. We’ll
experiment this year with putting them at the edge of a spillway -- an
environment they reputedly thrive in where they originated from.
LA
Bolbitis formerly attached to that ugly clay flower pot. We'll make
it into "plugs."
Bolbitis rubber banded to hard wood, rough rock, soft wood.
Bolbitis
Plugs. If you find an attached bolbitis plug for sale, don’t
tear it off and try to attach it to to something else. Just put the
plug on your driftwood and let the rhizome gradually grow onto your
wood. As you might suspect, this can take a little time. Once
again, we’re not talking hornwort growth rates
here.
LA
Bolbitis looks (and grows) best when attached to an appropriate base.
Fish
Threats. Forget plecos. Those destructive behemoths would
destroy your whole project overnight. Consider otocinclus, if you
need an algae eater -- or algae-eating shrimp. Keep out all large
fish -- especially cichlids (African or American, except kribensis and
rams) Exclude goldfish, and of course, koi. Put silver dollars
on your verboten list also. They probably don’t like
bolbitis, but they’d eat it before they realized
they don’t like it. Ditto tinfoil barbs
-- in other words, keep out all the usual suspects.
LA
When you get right down to it, bolbitis attachments aren't all that
strong.
Handle
with Care. Even though bolbitis attachments probably help them
resist being swept away by the current, the attachments can be
fragile. They easily pulled off that clay pot. Their attachment
to rocks are firmer. Bolbitis attaches best to softer woods.
Some of the wood in my original plugs could not even be sawed with a hack
saw. Some of those sinkable bog woods are either ebony or a very
close relative. Pre-sunk cedar seems to work easier.
LA
Bolbitis firmly attached to this piece of wood.
Last
Word. Perhaps we can agree that bolbitis is not for
everyone. You gotta really like these plants to put up with the
extra work. However, their slow-growing trait can also be one of
their biggest advantages. You CO2-injectors will get
faster results. We like bolbitis. And as we say down on the
farm: “What’s time to a hog?”
