I finally got my 60 gal tank up and cycled with plants, driftwood, etc. so I went out and bought 10 harlequin rasboras then transferred by betta, Foo, from his 5 gallon hex to the big tank. After a week, all are acclimated, but I think Foo is a little insecure with so much swimming room. Also, he invariably swims in front of the outflow at the right side of the tankand gets slammed against the front wall. Sometimes he swims around like he is comfortable, other times I find him hiding under a plant or wrapped around a heater (I keep temp around 80). Moreover, the rasboras grab all the food I put into the tank, including his Hikari Betta pellets. The only time he can compete with them for food, I have to dump a sizeable amt of frozen brine shrimp in or small bits of beef liver, which he loves. But the @#%$ rasboras go for the beef liver as well. I'm not psychic, so I can't read his mind, but I tend to think he may miss his 5 gal hex. Any advice?
