rummy-nose

Mirta

I have purchased seven rummy-nose tetras and put them in the 40 gal with neons, cardinals, silvertips, and cories. it seems to me the rummy-noses are the shyest of the whole collection. They keep to the ground and always together. Do they really indicate their happiness with the color of their noses?

My silvertips would attack them at first but have sopped doing it by now. They have actually become friendlier to each other. I would like to add some 7 black neons. It is a temptation. I hope it won't be too much for that tank. It does have hiding places now but nobody seems to use them.

Rummies are naturally tight shoalers regardless of the size of tank, tankmates and water conditions. As for the red coloration, it is an indicator of good or poor water conditions. If water condition is very poor, the red pigment will subsequently fade.
Tetras do not use hiding places unless intimidated, terrorized or insecured but those serve to make them quite comfortable in their home.

Thank you :) . The water seem to be normal, according to the tests. I thought , maybe their noses would be brighter as soon as they feel more at home? They are new.

I tried to do my best to take a pic of them today, but I am not very good at it . You could probably spot them in the corner as a rosy blurred group with red heads.

Your tank looks a bit empty. I'd suggest the use of plants particularly Java Moss. When did you buy the rummies? They will eventually flushed into deeper red once accustomed.
