archer fish shooting crickets 

Thanks man appreciate that. Maybe a puffer in the future, one that don't grow that big. Need to find myself some time to read information about them.

Thanks! i add salt to the water, just not enough to make it full brackish. cause of the ctenopoma and small catfishes.

@@nvalentijn Ohhh, but archers can live on freshwater? I have a wild caught archer, I'm trying to convert it to fresh. Please check my channel. Thank you. 😊

​@JzbyAquatics08 Most archerfish live in freshwater streams, ponds and wetlands, but two or three species are euryhaline, inhabiting both fresh and brackish water habitats such as estuaries and mangroves. Euryhaline organisms are able to adapt to a wide range of salinities. An example of a euryhaline fish is the short-finned molly, Poecilia sphenops, which can live in fresh water, brackish water, or salt water.

It's filled around 3/5

Nicky Valentijn what size is the tank though ?
