[Squid]

Just bought my self a 7 inch female P14 pup.
need tips, she is currently in a 12o Gal tank with my 10 inch Bd trio.
I've read they are more sensitive than Bds?
any tips? I've fed her some freshwater fish yesterday, she ate some fish.

Also do rays need strong pump?
currently my rays are in a 120 gal with 75 gal sump. the return pump is a Rio 1100. I've ordered a new 4000L/Hr pump.
Should i replace the old pump and use the stronger one?
