Yeah im still in 2 minds about sand, but i also think the play sand just looked lifeless(too clean), so could still buy sand and do part sand and part gravel
but sticking with super fine gravel for the moment
As long as you have adequate room in the tank for more cories, pandas and peppers will get along fine. If this is the 60 litre in your signature, it is starting to get fairly full already. I have you at about 16 to 18 inches of fish in that tank so far.
i used to have cories in my tank with gravel in and recently when i changed tanks i decided to go for the argos play sand which i found is excellent the cories look way more active and you can see them digging into the sand more then they could have possibly dreamed off. although alot of people say there cories are fine in there gravel you will notice alot of difference in the corys behavour. trust someone who has seen there corys change.
Agreed, i think it was the colour of the play sand i hated though, just too bright and unrealistic, so heres pictures of the progress of my new sand from my local Pets @ Home:
after adding the washed sand :
after a few more water changes :
even more water changes
and finally this morning i woke up to this :
in my mind it looks a lot more like natural sand now rather than bright yellow sand, and if i decide the sand is too dull i could always add a little play sand to brighten it up.
