I am planning my next tank, where I would like to transfer the entire population that I have in the current one and I am very fascinated by 3D aquarium backgrounds, for example those produced by aquadecor or Back to Nature. Are there any contraindications considering that I would be breeding Hypancistrus and Hemiancistrus subviridis? In the past I have often read that plecos, by gnawing, could ingest poisonous substances, but does this apply to all species or just some?

Not that I'm aware of, but it's a lot more fun to build your own. Hypancistrus are not known for being heavy "gnawers".

Cheers,

Thanks for the reply

Yes yes, building one is also an option. I thought the same thing, Hypancistrus are not great nibblers, maybe Hemiancistrus are just a little more, but not really that much.

I have had an Aquadecor background for years with no problem. They look great!
