Hi, I’m thinking on set up a 3 gallons Dwarf Seahorses tank. but I have a couple of questions before buying the staff.
I’m panning to set up this Aquarium, the filter will be cover with sponge filters to prevent sucking the sea horses
but I’m not sure if I need a skimmer? and if I do where can I found one? (one for 3 gallons)
I will put 5 pounds of live sand. about 2 or 3 pounds of live rock. and I don't know if I can add more staff, I’m not talking about fish, I want like small corals etc.
I also want to know if I have to do the 10% water change biweekly or monthly?
other than that what also do I need?
Thank You!
I’m sorry about my writing but my English is not good.
