I brought a male Honey Gourami home 3 weeks ago and he seems to be having trouble settling down. Originally, I put him in a 9 gallon Fluval Flex with no tank mates. He seemed happy and curious the first day or so, and then started pacing the front of the tank almost non-stop. Probably 80% of the time he is pacing.
After 3 weeks of watching him pace, I moved him last night to a 15 gallon flex where he has a small shoal of exclamation rasboras, 3 otocinclus and a Nerite as tank mates. He seemed excited about the new home until around noon today, when he started pacing again and hasn't stopped.
The tank is established with good parameters and is planted with a heater. He is eating and seems healthy.
I was under the impression that these guys could live without a friend. In fact my daughter has a single dude in her 10 gallon tank who seems quite happy with just his Corie friends. But I'm wondering if my guy needs a goirami friend to settle him down?
Getting a bigger tank is not an option for me, so basically my options are
1) Get a friend for him
3) Put him back in the Flex 9
2) Rehome him
Thanks for any advice!
