Hi all,
We've a 16g tank with 3 guppies, 4 tiger barbs, 1 plec (we'll be upgrading tank!) and 2 cories.
All water parameters are within normal range (although ph at 7.6).
Both cories were hyperactive but one has now taken to sitting still on the bottom. The healthy active cory will occasionally sit alongside and nudge the other into a quick spurt of activity and when this happens we've just started to notice the poorly cory rubbing/flipping, although not excessively (3 or 4 rubs).
Outward appearance is perfectly normal, fins fine, no spots/marks.
This behavior sort-of coincided with the introduction of the 4 barbs and one of them was initially a bit pushy with the other fish (although not the cories). The barbs have now calmed down and are happy in their shoal.
Any thoughts?
