I have three 7" to 8" Wild Discus stated to be "blue manacapura". They look like the pictures in http://amazon-exotic-import.de/Gallerie ... /INDEX.htm
for that fish.
Can you sex fish this size - Of the three - the largest is in constant display mode - for the two weeks I have had them. This is top and bottom fins extended, no black stripes and the body color is brown to red/brown. This one flashes the black striping for a few seconds and then they are gone. I am calling him "1" because of his straight lines. The other slightly smaller ones are Y1 and Y name after markings on their left sides. "1" and "y1" seem to be a pair and will bully "y" when food is added (black worms). After a while things go back to normal with "1" herding the other two. Mostly to the right side of the tank. These fish have been "in country" for a couple of months I was told.
I'm guessing that "1" is a male and the other two could be female. "1" does display fin movements to the other fish and then herds them over to a breeder cone I have in the tank. However I do not see any tubes down yet. There is hardly any cleaning gong on – what I am seeing maybe eating. Any body have an opinion on the sexing of these fish?
I just did a 20% water change and filled the tank with cold water (55F). and this dropped the temp from 86F to 80F. This caused them all to go dark black on their stripping over a light brown body. This lasted 5 minute and now they are back to there normal behavior.
I feed them once a day with a full worm cone. Most of the worms escape and settle down into worm balls on the sandy bottom (1/2” of sand). The discuses hunt them down over the rest of the day. Bellies are fat and the fish are very active. The strange part is that for wild fish – these are not afraid and will come and stare back at you. I also move stuff around to expose worm groupings which the fish then dispatch quickly.
I wonder if these were bred from wild and then exported to the USA. Are the fish exporters from that region breeding Discus now and calling them wild?
The future is what you plan for, life is what you get, enjoy it.
