Thanks for all the suggestions.  Most people seemed to think they were
'nematodes' and might or might not have been parasites.  In any case, I broke
everything down and reassembled the tank after washing the gravel well.  Seems
to have stabilized things.

One thing I'm now wondering about is exactly what one should and shouldn't feed
little critters.  I got a lot of comments about food; since there seems to be
some interest in this, I'll summarize the food-related comments I got (below).

Any other comments on (a) flake, (b) freeze-dried, (c) frozen, and (d) live food
(which kind?), with respect to (a) how nutritious it is, (b) how safe it is, (c)
how good it is for the fish?

"Roundworms" are simple animals, many species are not parasites, and many are.
They are nothing but mouth intestine and anus.  I think the phylum name is
"nematode" or "nemihelmenthys".  They probably didn't come from the brine
shrimp.  Few beasts can survive all the salt they need.  They might have been
from the bloodworms.

...                                                   feed only flake food and
freeze-dried food.

    Well, I can answer one of your questions: Live food *is* unsafe unless you
take enormous precautions to prevent contamination.  The frozen bloodworms
should have been fine (provided you bought them from a reputable source, as
opposed to "Joe's Generic Frozen Fish Food"), but live brine are a definite
risk.

                                  there were these little wiggly things, about
2-4 mm long. I fed only dried food in those days, but one of the dried foods was
freeze dried tubifex.

Where did they come from ?  Bought any plants lately ?  They, in all likelyhood
cannot have come from brine shrimp as marine parasites don't fare too well in
freshwater. But the plants are suspect.

It *is* possible thay came in on frozen food.  One of the better foods for very
young fish is microworms, which you culture on oatmeal.  These cultures only
last a week.  So you have to keep making new ones. Well it turns out that you
can freeze them, and they do just fine.

I'm not certain that any parasite could survive freeze drying, but it wouldn't
surprise me.

I've used frozen bloodworms with no problems.  I have trouble with live tubifex.
Fish always seem to get "the crud" after I use them.

Live food is a bummer unless your fish absolutely require it, and then one has
to be extremely careful to monitor the tank for parasites and other undesirables
that are introduced into the tank with the food.
