Kuhli Loach Acting Weidly

[ghhghh]

hi i'm new here and I have been keeping my tank for now 2 years I got some
kuhli loaches the other day and they were all hiding but now
2 of them are swimming around the top and middle sections of the tank, even when the
lights are on (Don't normally like lights)
please can someone tell me whats wrong with my fish and how to cure
it?

How many gallons or litres is the tank.
How many fish and which type.
Water stats in ammonia, nitrite, nitrate, and ph.

i have these fish.
there odd to say the least but cool.
with these fish, same as any other fish you cant garuntee they will only be active at night....the fish will do as it pleases once settled into your tank.
my loach swims happilly around during the day with the tank light switched on. and also at night with it switched off.
it east normally. and is a happy fish.
once settled into a tank they can occasionally become very active and up-front.
there is no cure to your problem as the fish will do as it pleases.
and dont worry there is nothing wrong with your fish.
they sound like happy lively fish to me.

good luck with them.
