Anything I need to change?

Hi, just wanted your advice on my new albino plecos with the long-fin gene (dad is a long-fin, mom is normal)

They came in the mail, all alive even the DOA one so I have 7. I did the math and found out I got them for $4.10US so I guess I got a good deal, none of them have long-fins but hopefully the babies will.

I put them in my 10g for quarantine and since it is my only tank with driftwood, I figured it was best, just until I get my 20g and 30g that will be set-up in no more than two months

I am dosing exel and flourish for my plants, doing 40% water changes weekly, is there anything I need to change?
