Normally if a fish has a parasite its common practice to do
hyposalinity which is when the SG is reduced to 1.019. The influx of
more fresh water kills the parasites. It works. I can;t say about high
sg doing the same. I run all my tanks at 1.026 since I like a reef
tank, and have never had a problem. At one point in time I used to
run tanks at 1.023 and 78/79 or so degrees and they did alright, but
at 1.026 and 81-82 deg they do fantastic.

What I would like to know is why neon gobys copst as muchs they do for
them being easy to tank raise, or at least thats what I have been
told. Here they sell for $20 for a NG of 1/2-3/4" length. Sure was a
bargin that day they had 1 to 1.25" NG at Petco for $9.95. It was the
one and only time they have ever stocked in any neon gobys.
