| Re: stocking plan for a 5 gallon. Possible fish choices would be Trimma sp. that reach about 1 inch in length, they are a cave species so if you go sps I wouldn't recomend.
The host gobies, Pleurosicya sp. is another choice that stays under 1 in in length and is found associated with sponges, sps corals, clams or soft corals.
I do recomend keeping them 10-15 gallon tanks only because feeding fish if very difficult in a 3-5 gallon tank without polluting the water. It's much easier to stick with shrimp, snails, and hermit crabs in such a small aquarium. |
