Hello, I used to own a few fish tanks years ago when i was younger and decided since i had some friends getting rid of tanks i would start again. When i had fish before i was quite a bit younger and took what ever the fish guy in wal mart said, i'm a lil smarter now 'little'. so i put the first tank together and let it run then bought the fish, this time i just took what the fish guy at petsmart said as fish 'word' haha bad idea. So my tank at that time consisted of 2 tiger barbs 'she told me 2 was fine' I later learned that they need 5-6 to school or shoal or what ever. 2 rainbow sharks 'she told me 2 was a good number' I later read that rainbow fish are not good to have more then 1 in a tank. 1 tinfoil barb 'she told me yea it is a solitary fish' I later read that these are also schooling fish and get over 10" witch will be way to big as a school for my tank. a pleco, witch is fine and I added a beta to test what would happen with a back up tank in case. They actually got along fine weird enough the tinfoil schooled with the tigers, the 2 rainbows ignored eachother although the 1 is much bigger now then the albino and well the pleco was just that. I was still worried about the tigers nipping if i didn't get a school so i went to petsmart armed with more smarts then last time and new what i wanted to get 2 more tigers and mabe an oto just to clean while the pleco was soo small att this point. well i came home with 2 tigers, a powder blue groumie, 'spelling'. but now the tigers are starting to nip a bit was 4 enough or did changing the layout mess it up how would i go about ending the nipping adding another 2 tigers? that is what i've read but when the tinfoil grows he will deff over stock the tank this is in a 30 gal btw.
