Thank you!

Thank you very much for watching! Much appreciated

Do you have a link to it?

Last study I saw ~24% of their diet was mollusks and 60ish percent was insects, the rest various little odds and ends like small fish

Some people say they do but mines have never really been interested

Yes, they do if they get scared. I’ve seen one of mines puff up once

Yes we do. What is your problem?

I have 6 SAPS. All of a sudden gone off their food but nothing has changed. Water changes done regularly and parameters good. Just not interested in anything I give them. Also glass surfing again more than I would like :( do you think they are fed up with their tank mates? Could it be lack of space? Could it be my lights are too bright as they calm down when the lights dim in the evening. I'm so worried they are stressed! Thanks in advance

What size is the tank? Is there plenty plants and hardscape in the tank?

35 gallon tank. It's fully aquascaped with live plants, rocks and wood.

It’s maybe on the smaller side but wouldn’t explain their change in behaviour? If they calm down with the lights dimmed try and feeding them when the lights are dimmed. You could also try live foods like blood worms or mosquito larvae to try and get them eating again.

You’re thinking of Green Spotted Puffers. Amazon puffers are fresh water pufferfish. In the wild they do migrate to brackish areas for small periods of time but in the aquarium hobby they should be kept in freshwater. I’ve had mines for over 4 years
