It probably needs more light. I had a bunch grow like crazy in my little 5 gallon refugium with 2x13watt bulbs but when I upgraded to a 25 gallon refugium the chaeto started to dwindle and what was previously football sized shrunk to the size of an orange even with a lighting upgrade to 2x23 watt bulbs. I added a canadian tire fixture with another 23 watt bulb and the chaeto is flourishing now. I'm even thinking of putting a stronger bulb on there if I can find one. Definitely try the more light thing to start before you start putting any additives in or something like that.
