In my 30G I have 10 neons, 5 Green Tiger Barbs and 2 German Blue Rams. The female rams looks ready to breed. In my 10G I have 17 swordtails about 3/4"+. On Saturday, I managed to get 17 pineapple swordtails (1 is actually orange) in the 30G and the 2 rams into the 10G to breed (not sure if rams will breed in 10G but I thought Id try). I guess my plan was not such a good idea. I did the switch late Saturday night so the lights were off in the 30G. It gave the swordtails time to adapt to the 30G. Sunday morning I was watching the 30G and counting the fish. I noticed the orange swordtail was hiding and cowering in the plants (didnt know why). Then she darted towards another clump of plants and to my surpise the neons were after it but quickly decided the fish was to big to eat. She was around 3/4" big. I came to the conclusion that colors attract other fish. The neons did not go after other similiar sized swordtails. The barbs however did not give up chasing the orange swordtail. I have heard that "if the fish fits into its mouth, it will eat it". Not true for the barbs. The barbs did manage to catch the orange st and managed to suck its tail into its mouth but could not eat the whole fish. It then tried the head and same thing. The poor little st was pretty much a goner. Ok!! No problem! Maybe it was just the color. Nope!! Few minutes later, the barbs had another similar sized st that it could not eat but nevertheless tried. So, I was left with no choice but to take the st's out again. This did it for the barbs. I'll be taking them back to the lfs and exchange them with some discus.
I thought Id just share this experience.
