I recommend Imperial Tropicals. I have no association with them other than that I ordered twice from them in the past in 2018 and I just placed an order a few hours ago.
They are doing their annual Thanksgiving/BF sale. 20% off their prices and the prices are their normal prices as I check their site regularly and finally decided to replenish some of the fish I've lost over 4 years time. They also have some BOGO sales.and every hour right now on Black Friday, they are doing flash sales.
I wish I had more room as I'd get the BOGO Bosemani. Instead, I ordered panda garra as I only have two left and my pleco died earlier this year.
I cleaned them out of the 6 they had remaining in stock.
I also got 3 Dority rainbows (1 male, 2 female pack. I originally had 4 males, 1 female from Divers Den liveaquaria, but only have two males and one female left),
3 dwarf neons (also 1 male, 2 female pack, as I also have 2 males, one female left in my tank of those).
I ordered one female albino millennium (I have 1 male regular millennium and one female, and 2 female albinos and one male).
I have three deep water creek melanotania splendida (again two males, one female). They are out of stock of those but I read these variants of m. Splendida will swim together, so I got one male, one female of the Upper Katherine River variant (all they had left), and 3 unsexed Fletcher Creek rainbows they had left in stock.
They had a promo video that showed some of the fish that will be on the flash sale, and those Fletcher Creek seem like they will appear as a flash sale so I may get some more of those if they do appear.
As you can see, I'm excited about getting new fish, and that should be seen as a good endorsement of this place. I had no problem getting orders from them last time delivered to IL.
As mentioned, I also had fish from liveaquaria Divers Den. They were fine and I still have the three clown loaches I got from them. I liked their quarantined Divers Den fish but the seemed to have stopped posting new fish on their over the last few weeks. I don't know if they are taking a break or shutting it down.
