So ive been noticing my delhezi swim very weird the last few days. I didn't think much of it but now its getting worse. It seems when he swims up to get air he can only use his two front fins and his tail doesn't move at all. Its like hes stays completely stiff when he swims just moving his front fins. I thought it might be a broken back but idk if thats it. Also he has been shaking his head and sort of twitching. Another thing i thought it may be is parasites because i have my african pike that i just got in with him and the pike only eats live foods right now. I put the feeders in my 10 gal with parasite meds before i feed them to him and i saw my del eat a feeder. The water tested good and im going to do a 50% wc today. If anyone knows anything about this let me know.
