Hi, I looked into Divers den and did not seem to find any freshwater abei puffers.
Feel free to chat about how to find a true abei or how find the website.
We're in the US too.
I can't help with your current tank issue, but I do have a tip for your future puffer tank.
In my tanks, I experienced a lesson learned for leftovers.
-larger species of puffers...
Add fry***
A simple (symbiotic) relationship between the larger fish and the fry seems to work well vs. time.
The 5 inch Turgidus puffer pair and a 6 inch palembangensis puffer pair can't catch the fry easily or at all.
The fry peck away at food chunks, but can only do so much.
These fry age and "eventually become a food reserve" as Mod/Pufferpunk stated in the past.
I agree.
They usually get eaten in the night.
When the lights are out, the guppies may be in a sleep state.
I personally see the small cutcutia puffer pair or even the paulustris puffers getting a hold of the fry in short time though.
Smaller 2-4 inch puffers are quite fast and seem to not give up so easily.
They terminate the prey items.
Absolute machines.
Observation:
Bigger puffers + small fry.
-Reduces leftovers slightly.
-adds bioload slightly (fry or living house keepers).
"Try" bare bottom styles for cleaner tanks, then add substrate later if you feel the need.
I have been running mostly all bare bottom puffer tanks with added sandbar/beach style smooth rocks from the stream in the backyard.
Plants are a plus if they work out. I'm about to turn a small 20gallon over to a small puffer this weekend.
Some puffers like to chomp on wires and plant stems as a food test or something.
All my puffer tanks are so different.
I'm still learning.
Some like half lighted LED and half darkness and driftwood.
Some even like half current flow and fuller current flow on the opposite end.
It gives them lighting and water current choices.
As for the real world, I was amazed at how bare the stream was for vegetation in the video I saw about a wild puffer in Thailand.
The end of the video (posted below) near the 3:15 min minute point has the part where he comes out of the water and shows what the stream and forest look like.

(video) If that was not a puffer in the river I would have sworn the video was taken in OH, PA or Michigan or something close.
I was pretty blown away at how similar the creek looked.
There may be crayfish and weird grubs under those rocks.
Lots of hidden foods.
