I will.. lol They are just babies anyway.. Im sure a 2 inch fish doesn't need 55-75 gallon rectangle tank... Heck breeders keep 5-7 adult sized discus in 20 gallon tanks...
Discus hans have you seen his shop ? All his discus he sells Do you think he puts them in 55-75g tanks when he grows them out ? He packs then in crammed 20-30g tanks.. and it takes a year for them to grow to adult size.. So im sure 3 will be fine in a 44g pentagon.
Babies or not, they do require many things that it sounds like you're just not willing to commit to or are trying to re-write the book of Discus on. And fwiw, I know of NO breeder that keeps 5-7 adults in a 20g. Since you know who they are, why don't you share for the rest of us ??
As far as Discus Hans goes, he's got 30 more years of keeping, breeding, raising, and selling than you do. And that's not even bringing up the NUMEROUS awards he holds under his belt. I communicate with him on other social sites and he's quite fond of the advice and knowledge I share with Discus noob's.
As for his Discus that he sells, some of them do go into 55-75 gallon tanks. Not all, but some. But let's also bring up the fact that they're only in his facility on average of 2-4 weeks and in that time he does more WC's than you can imagine. Also, it honestly does take about a 10-14 months to grow out a Discus so no points on creativity there.
As for the tank and everything you got with it. It's only 30" at it's widest point which is about 18" shorter than the minimum recommended length. Something Discus really need to reduce stress (along with being in groups of 5 or more) is lateral room for movement, so I'm sure they won't be fine. It's the very difference between surviving and thriving.
Now with all the other stuff that came with the tank, it's very clear that this was a SW setup from the previous owner. The lights and power heads are a dead giveaway. The auto feeder is junk. They always have a high failure rate and are better off as a paper weight.
Do the Discus a favor and leave them in the 55. They're much better off there. Do yourself (and them) a favor and spend your money on two more instead of new stuff. Because in post #4, all this stuff was great and in #22, it turned into "this guy gave me junk and I'm replacing it all".
So to brink it back to your original question of do I think you made out good, for the equipment value to money spent, kind of but not really. On your plans to use it for a Discus tank, big fat zero. Ideas to replace equipment instead of creating a better, less stressful environment for the fish, another big fat zero. So overall, (1-10 scale, 1=poor-10=great) I'd have to give it a 2, maybe 2.5. Just my opinion.
