Can fish have brain damage???

Black streaks on fins could be ammonia burns that are healing. Get ammonia
to 0 (also get your own test-kits if you can).

Goldie being nudged? hmm sounds like your goldie could be egg bound possibly.
Can you get hold of any medicated food - its possible that might help.
Try salting the tank (aquarium salt only). 1 table spoon per 3-5 gallons or
so, dissolve then add. See if goldie perks up after a few hours.

Anyone else got any suggestions?

I think it may just be Blackfin... It likes nudging Treasure too... Goldie is
still not eating - not even her fave shrimpies... Just kinda saunters around
in little circles... Can it be so brain damaged it doesn't know to eat
anymore?

I'll do another partial change on the tank. It's cheaper to have the LFS do
the testing. The kits are a bit pricy and they are only a mile away.... If
Goldie doesn't perk up in another dayish, I'll put it back in the bucket and
try to get it to eat... Thanks so far for your help!

What colour is fishies pooh? Also do you have gravel? When fish are ill they
sometimes don't eat. If swallowed a piece of gravel, won't eat also.

Took the gravel out last year. The other fishies' excrement is normal and
short. Goldie doesn't have any (that I've seen) as since nothing is going in,
nothing comes out.... Did a 30% change again yesterday... Will check the
levels later today....

does the ill fish open its mouth at all??

Yes, it does open its mouth. The gills are pumping too... Just seems to swim
around in a daze though... The others target for the food when fed, but Goldie
"just keeps on swimming" like Dorie from Nemo... (that song is sticking in my
mind) Doesn't notice the food at all...

try hand feeding
