Think it'd be fine for me to add a group sajica to my vieja growout tank. Tank is a 125 gallon. My sajica are in a 90 with some other fish but am afraid things will get out of hand in that tank it they decide to start breeding. I have two for sure makes and one for sure female and another possible female. My vieja are all 4 inches and up. Sajica are around the 3 inch range.
