Can you keep freshwater fish in low brackish water?
ninety_sixmustang asked:
I have a 40 gal freshwater set up right now with Barbs, Danios, loaches and a rainbow shark. I want to get a spotted green puffer but read that they are brackish fish. Would I be able to make my freshwater slightly brackish in order to keep a spotted green puffer or would that mean death to my freshwater fish? Would I be able to keep the puffer in a completely freshwater tank??

The order Tetraodontiformes contains Porcupinefish, Triggerfish, Boxfish and the Pufferfish are almost entirely found in the tropics and subtropics. Only a small amount are found in fresh and brackish water and they all belong to the pufferfish family. One of the more common of the “rare fish” The Green puffer needs special care and should only be kept by the more advanced hobbyist. This fish is usually wrongly named Tetraodon fluviatilis.

Mollies, swordtails, and some fish like the Indian Glass fish would be ok. But I think with the fish you have, the level of salt would be low for the puffer and high for the others. Nothing would live anywhere near it’s normal life.

You would have to slowly add salt to your tank, Say a cup one morning, then a cup that afternoon, Eventually you salinity will be enough for puffer and your other fish would be acclimated

What I would do, is gradually raise your tank into brackish levels by slowly increasing the salt levels over the course of a few weeks. This would minimize the stress on the fish in your current tank. Before doing so I’d check on the sensativity levels of salt to your Loaches and Danios. I do not know this off the top of my head, so look at it like this. Let’s assume it’s not reccomended or advisable to keep Danios and Loaches, or anything else you currently have in brackish conditions. What you’d then want to do is just establish a new tank and acclimate that to brackish conditions. In most cases, if you slowly raise up to brackish levels, the current populations just adjust because you raise it slowly and not suddenly. Just check the compatibility of your current populations to living in brackish to see if this can be done. I’d tenatively say yes pending what the population can tolerate, but just raise it up very slowly.
