I am about to buy a 20 gallon tank and am desperate to get a puffer or two to put in it. I have done my research and am now not sure whether to make it brackish or freshwater as I don't know whether to get 2 red-eye red-tail puffers or a south american puffer in freshwater or 1 or 2 figure eights in brackish.
The only thing that puts me off brackish (I love the figure eight puffers) is the extra investment in salt and a hydrometer, I am on a budget, and the SG
confusion. However I also have 3 bumblebee gobies in freshwater at the moment and I have read they do well in brackish and get along with the figure eight puffer (although my water chemistry is hard and alkaline, about 8.0, and I have read that they can be kept in freshwater in these conditions with no problems, and they have been doing well).
The good thing about the red-eye red-tailed puffers is their smaller size and so could I get more, like two pairs, in a 20 gal
? But would they get along with the bumblebee gobies? Same goes for the South-American, and would I be able to have two in there?
Sorry about the rambling
, I was just wondering if anyone had any advice or strong opinions about the puffers or could help me weigh up the pros and cons.
