Re: Super fast swimming bugs

[Steve \Srfmon\]

I'm willing to bet that any night time bugs are okay for your tank. It
sounds like you are talking about mysis shrimp or maybe just some type of
pods. Both are good things to have (great detritus eaters).

usually amphipods and copepods both really good to have, they are part of
your clean up crew, you have more now because it went fishless for a while,
and there were no preditors, and generally there is always plenty of food
for them.

a note if you find something dead, it will be covered in them ***they didnt
do it!!!!***, many different species are scavengers and will make a meal out
of a dead fish.

Sounds more like cirolanid isopods. Much faster than any shrimp and large
enough to see moving around the tank. Put your hand in the tank at lights
out, with a piece of shrimp in it, and they should swarm the food. If you
are lucky, one will bite you, a rather interesting type of pain! Most of
these guys are scavengers, but others will attack living fish, if so then
you have a problem.

look up isopods... if they really small try copepods..
