Thread: Hiding corys
12-27-2012, 09:29 AM #1
I have a 125l tank and have 6 spotted corys.
there seems to be 3 bigger ones that are visible in the tank, yet there are three slightly smaller ones that hide constantly underneath one of the ornaments in the tank. (its ruin with a hollowed out bottom)
i have been told not to worry, but i never see them unless i move the ornament.
Is there anything i should worry about? or is it just that they arew smaller?
BTW, have my water tested once a month, no ammonia, or nitrites and very low nitrates, so dont think its water quality, and i have deliberately gotten 6 plus 3 smaller black corys so that there is a decent number to avoid bullying.

Do you know specifically what species they are? You've done the right thing to get 6, but only having 3 black ones - they'll want a bigger school too.
I have two schools of cories (peppered and sterbai) in my 120 litre and whilst they mix readily, they do prefer their own species' company. The sterbais I have are very shy and hide a lot which is normal for them. The peppereds are very relaxed and brave.
I wouldn't worry about yours, it may just be their species type. I would get yourself a liquid test kit though and test every week or two (or just before a water change).

I was thinking about adding a couple more black ones.
Yeah, have been really careful in following the advice of the guys in the shop in regards to schooling and looking after the tank.
Again, as you have said, its probably that they are shy, but its a little frustrating as they look cool when they are all out and about, but dont seem to see them.
Im wondering whether the fact the lights are pretty much brand new and kicking out full power is an issue? that is why i got a few ornaments to hide out in!

Just fake plants,
Im still pretty new to the hobby so didnt want to overcomplicate things just yet.
As another brief question, what is the general rule of thumb in regards to stocking?
Is it 1" per litre (within certain boundaries)New Guy!!

No - you can only use that rule for very small fish that STAY small - like neon tetras.
If a fish can potentially grow to 10" you aren't going to keep it in a 10gal tank LOL.
BTW you were trying to avoid bullying by what? What else is in the tank?
