I just recieved 6 Half dollar size angelfish from a breeder the other day.I have them in a seperate tank (quarantine) a 29 gallon.Looks like 2 of them are pairing up already.They were cleaning the filter intake tube,and chasing the other angels away.Do I get a divider or put the others in my 90 gallon with 6 other angels that are in there now?I do have a 20 gallon tank,but it' not cycled yet.Also,if I leave them in the 29 do I put a sponge on the intake tube?
