i lowered the temperature when i made the thread. the temp gauge goes by 5 degreez, so its a bit of a guessing game. i lowered it again yesterday. i think its sitting at 78-79 now. i did not add airstones, but when i made the thread, i took out a gallon or two of water, to leave about an inch of space up top, so the flow hit the tank water harder. and i did a WC yesterday, and left another gap. so i really feel like theres enough oxygen, especially since the other person said that the filter should provide enough agitation. however if there is other opinions on that, i could be compelled to run out and get one.
the fish are still behaving the same way. all the barbs are at the very top of the tank, nose nearly breaking the water. occasionally 1-3 of them will drift around. the GBR's and my pleco seem PERFECTLY fine though. i just do not understand!!! i dont know if i just got screwed up tiger barbs, or theres something weird with the water chemistry or what. i recently stopped feeding them my crappy flake food, and now feed them frozen daphnia and frozen bloodworms (i trade off here and there)...that couldnt have this type of effect right? after about a week or 2 of feeding them the frozen food, they started doing this.
