Hi. I have a small number of RN tetras in my aquarium. I introduced some new fish today and all seems calm and all happy. The only noticeable change is the noses of the RNT have visibly gone very very red - vibrant - which I haven’t seen before. I’m assuming this is just a reaction to the new fish and they feel threatened in some way? I just think they’re over-reacting 😂. The fish introduced were 1 bristlenose and 3 Siamese algae eaters. I’ve not noticed this happen with new fish before. I’m not complaining. They look stunning.
