Personably, I'm not a fan of invisible set-ups. But that's just my opinion I think it's kinda stressful too the fish, as they bump into almost everything in the tank.
yea same here kinda hard to see where their going...wonder if they got the food i drop in for them? hmmm.....lol man what if you had a 180 gallon and had a Red Tailed Catfish in it for over 3 years...man you won't even be able to see it even at that size! lol
Well, since everyone else is posting pics of theirs figured I'd add one of mine...btw, I haven't done a water change (ever) in this tank, it has no heat...no lights, no filters but the fish are all doing wonderful!!
