Any ideas? I'm fairly new to saltwater. I want to get something. I've slowly increased salinity over about a year and a half, it's now at 1.022. Tank is 30 gal, 20lbs live rock, couple caves, red seaweed. (willing to use my 55 since it's only housing 3 leleupi now) I've had success with other tankmates in the past but traded them in when the salinity got too high (figure 8 puffers, mollies) Something bright that gets no bigger than 6-8 inches would be ideal, and something non aggressive and fast would be a must. Appreciate any input.
