getting back into saltwater. I moved and have a stable home. I happen to face the ocean and the itch is back. the last time I sold my tank when i moved away . I rather do small water changes more often then big ones. so I am drawn to smaller tanks. I'm trying to decide on what tank to pick. there is two I am interested in. one is 60x32x27 the other is 80x40x40 . (cm not inches )considering my favorite type of inhabitants all care about floor space over volume. do you think the small tank would be fine for a few fish and many hermit crab and corals. or would there be a big enough difference to justify getting the much larger tank even though floor space increase is minimum? I'm a bit stuck on what to go for.
