I have a question. Can P's see in the dark? I know once the timer on my tanks go out, I hear more scuffle in the tanks (especially the Rhom tanks) then when the lights are on. Or is it just my fish??

yes, they can see better than we can
some people say their Ps become more active when lights are out, they can tell because they ca see the reflective scales on the fish flashing all around

I have heard this before myself. Not sure where but I have heard that threre eyesite is almost as good as humans. Supposiblly the "lateral line on the flank" allows them to see objects under least favorable conditions (dark murky waters). Don't know if this helps at all?Xenon said:Could you elaborate on this a little Frank? When you say "lateral line on the flank" what exactly do you mean? I knowhastatus said:flank means side so they can "sense" things in low light conditions?!![]()

Its not radar in the visual sense if that is what you are meaning. The lateral line (mid line) are horney grooves (bones) along the flank that runs from edge of gill anterior to posterior end of caudal peduncle bone. It is sensory organs that detect fluid motion either from other fish or in some cases objects a fish approaches. That is why catching them with hands or net is sometimes difficult because the lateral line detects this motion before the eyes do. Another good example is blind cave fish which have adapted this as "eyes" and strong oral factory senses to detect smell. I'm trying to keep it simple. Good test/example try catching the fish from behind with net slowly. See what happens.

the lateral line is probably one of their most important organs, it senses pressure changes
it can tell the fish current direction, where other animals are and all sorts of other things

yeah it consists of very small fine hairs that can sense all the conditions surrounding then. As well it is also believed that they have a good sense of smell
= neuromasts.
Actually, proper term is known to have a good sense of smell. That has already been established.
Actually, the lateral line is one of the most important survival tools for fish (especially smaller ones): if pressure changes reach their lateral line (for example caused by a fish-eating bird that dives under water), it causes the fish's muscles to flex unvoluntarily: this often safes the fish's life, because it makes him dodge the attack, even though it may not even have noticed the predator at all.....Sir Nathan XXI said:
