the tank is a 30 gallon tank. i think i have 10 tiger barbs. maybe 12. i forget.and i have one bristlenose pleco, and two german blue rams. ammonia is 0, and nitrate is at around 10-20ppm. i do frequent water changes just to make sure everything is going well. now, when i first got my barbs and they were the only thing in the tank, they were going from left to right in the tank. i put in a red tailed shark, but took him out because the tank is too small, and he was picking on the barbs. i went thru a case of ich as well. then i got my pleco, and my two gbr's. everyone gets along quiet fine. if anything,the gbr's seem to bully the barbs.( you can see in the 3rd picture the two rams are chasing the barbs) so now you have a little info and history on the tank..my question is..why are my tiger barbs not very active? most of them eat when i feed them (frozen bloodworms/frozen daphnia) but 2-4 of them sometimes dont eat? some of them will randomly loose some color, and lose control, and float nose down? some of them linger at the very tippy top of the water? but they are ALWAYS chilling in the green bamboo on the left of the tank. i dont understand!!! even if i put my finger in there, a few weeks ago they'd all be going for my finger. now its just the two (VERY curious) rams, and a few select beefier-than-others tiger barbs. the only 6-8 or so barbs just chill out in the plant. should i take apart some of the bamboo (they have little connecter things) and give more swimming space and less hiding space?
