No, there's a tank called the Pico Rta.
It's a top fill tank that you can coil yourself or may accept CLR coils .
It's a great mtl tank but i don't like it's look.
You can find it at fasttech (cloned) for around 10€.
There are several models available, check carefully as some don't have the CLR adaptors.
Yeah - @Katdarling has one, but I'm not sure it's getting a ton of use. I think there may have been something about the adapter that she wasn't crazy about. I had one too but didn't hang onto it for long.
I usually remove my tanks to fill them (had some bad experiences), regardless of top or bottom fill. I have some of both (top & bottom) that I both like and dislike, so that issue (fill) isn't a big one for me.
