Wow... really glad to see they're perking up!

I see that you've already added an air stone... I was going to tell you that... you definitely need an airstone in there... or two... or 100!!!! (ok, not that many).

They're looking good!!! Nice!

As to the transplant... EXPERIMENTAL IDEA:::

Why don't get a big soil pot... then fill it up with one of those super soil recepies, and dig a hole on top the same size as your current (small) pot.

Then, install the smaller pot into the hole, make sure it's super compact with soil... ok ready? here we go... now smash the smaller pot with a hammer and some pliers... take out as many pieces as you can...

Do you have a Dremel? You could saw off the bottom of the pot...

Anyways, ... Ta DA !!! What do you think?
You could change the super soil for some more hydroton pebbles... or some lava rocks...

???
