riding current for fun or oxygen

[DJ-don]

i hav a 145 litre tank which recently got fully cycled and i added 2 full grown opposite gender

Ancistrus cf_cirrhosus

and it was riding the medium - strong current alot. is this just for fun or natural behaviour, or is it an indicater there isnt enough oxygen in the tank, which i highly doubt because there is alot of plants in there. 2 11 cm hygrophilia 1 big amazon sword 1 massive clump of java moss and small java moss added to pots and such
ammonia and nitrate/trite levels are at 0.
p.h. 6.9
softness 30
just trying to make sure if anything is wrong.
i dont want to risk anything
much help is appreciated.
and also i went to other forums and all of them dont tell me anything about blue rams if they mind currents. i know this is a catfish website but i was wondering will these fish go well with the current? thanks help is appreciated

Most plecos like to sit in current from time to time. I'd worry if they start gulping air from the surface.

ok cool! thanks for the quick reply. im just checking to make sure and there is defintley no gulping air!
and what about the blue rams Plan to add them later

It really depends on how much current there is in the tank. The rams like a little current, but not too much. From my experience....they tend to stay away from direct current.

Even when the water is well-oxygenated they may do it the odd time. If they are doing it a lot, that's when you have a problem.
