So my xingu paired up and started spawning about a week and a half ago. They were in a 450 gallon with very high flow rate. Yeaterday i finally moved the pair into a 300 as i was worried about the other bass in the original tank that i am currently trying to sell. Question that i have is about flow rate. I have noticed that they are now alot more lethargic this morning. I know that i just moved them but i have never noticed my fish just sit on the sand. I added a powerhead into the tank and they almost immediately started acting as they usually do. Problem is my only powerhead i have right now is like 1000 gallons per hour and im worried that the current might be too strong for spawning. I never bred pbass so any advice is appreciated . Do i buy a smaller powerhead and see if they go lethargic again? I was even thinking of using the 1000 gph to feed a mini gravitysump and have the watet just shoot straight down so theres flow but not crazy side to side action. Or are they fine in high flow?
