I have 2 neon gobies in a 20 gallon quarantine tank. It does seem a bit of an overkill size-wise, but that's not the problem. The larger goby claimed the whole tank and terrorizes the little goby whenever he makes an appearance. The little goby hides in the 1 CM space above the powerhead. The fish can't jump out, but I'm worried that a stressful quarantine will be bad for the little guy. I already plan on moving him to the show tank before the larger goby so he can get established. There is plenty of LR in the 45gal, it's a reef tank, so I'm sure they can each make their own territories. I was wondering when the earliest I should attempt this is. I was originally planning to leave them in quarantine for 4 weeks minimum, but they've only been in the tank since Sunday evening (4 days now,) and things look bad for the little guy. He's active above the powerhead, but he can't come out without being attacked. I'd love some help with this.
