are they the smallest of the freshwater skippers? what are the other varieties that are ok in freshwater?
To my acknowledgement, Indian Dwarfs are the smallest. I do belive that there is another spices of a dwarf skipper out there, but I really cant think of it...
And as far as the freshwater goes... You should understand that it is still reccomended that you keep the skippers in brackishwater. Personally, Id only advise the indain dwarfs to be kept in freshwater, (personal experince) Any other skipper that you will find that can be kept in freshwater, will be a bit rare, You will have better luck finding the indians.
The main thing that you should think about when concidering on setting up a mudskipper tank is the set up.
So many people have just a few pvc tubes gluged or stuck to something, and thats the only "land" that they give for their skippers... I have seen this way more times then I'd like. I have even seen this on a few websites as a reccomendation to do, but honestly.... Does that seem right to keep any creature on a 2~3inch pice of tubing and say.. "enjoy"... NO!
Id reccomend doing part water, part land as a set up. Some skippers can even be known to dive deep into the water and eat small fish or fry.
Mainly, you want to try to make a very natural setting.... (rockwork, driftwood, ect..) Id say.. stay away from the pipe work..
Heres the link to my mudskipper / community tank...
