 Re: solitary otocinclus?
Yes they should be kept in groups. They suffer psychological stress if kept alone or in small groups. 3 fish is the minimum recommendation, but I have always felt that keeping them in groups no smaller than 5 or 6 was best. They still seem to act stressed in groups of 3.
Yes algae tabs will work well for feeding them. They will also eat flake food that sinks to the bottom. Or blanched/par-boiled zucchini. |
