Since tubifex normally survive warmer conditions than blackworms, there
is a corresponding higher likelihood they will have fellow-travelers
that are able to survive our tanks. They may not be a vector, but their
water may contain stuff we don't need. Flush thoroughly and frequently.
That said, 99% of the rumors about worms carrying diseases are just that
-- rumors. They don't spread *Camallanus*, AFAIK, or Velvet or a host of
other diseases. The Asian species of *Camallanus* have free-swimming
larvae and need no vector. Daphnia, Cyclops and insect larvae are more
likely hosts for those species that do need an intermediate host.
[The *Camallanus* rumors are reinforced, because those things dangling
from the fish look so much like tubifex!]
What they often do is greatly enrich the diet and amounts of ammonium
produced in the fish waste. That quickly degrades water quality. The
opportunistic diseases that result are never blamed on the husbandry
practices of the fishkeeper. It is easier to curse the store and say the
worms brought in the [insert favorite opportunistic disease here].
Would it be worth the trouble in rigging up a UV unit for a tubifex
recirculating tank, or is UV not effective against 'whatever' that comes
with the worms?
No answer possible, unless you can define that "whatever." :-)
I used to put a few ounces of tubifex in a quart jar standing in the
toilet tank, and they lasted as long as I needed them. They even got
How long did the worms manage to survive? If you started off with worms
in good condition, they can last up to a week in a unaerated shallow
tray of detritus and mulm. A bad batch will muck up the water real
fast, be it in tray or toilet cistern.
Probably not in the toilet tank, as every flush replaces the fouled
water and debris, and gives surviving worms a decent chance to go on.
Mine, as I recall from almost 50 years ago, used to last a month or more
(until all were fed to the fish, basically). I never got any in bad
condition, so can't speak to that part.
BTW, deep water isn't as bad on tubifex as on blackworms, but they need
cool oxygenated water for long-term survival. A small ball of them in a
deep toilet tank worked because they were cool (<60F probably) and had
few worms to several gallons of fresh water, changed often. Chlorine
didn't bother them in the slightest.
