Nicclem Posted March 8, 2021 Share Posted March 8, 2021 (edited) One of my guppies is becoming red, internally? He is normally a pale yellow, but the past two days I have noticed his chest area/gills (not much but I think more than normal) and now his body have become red. He is acting normal, maybe slightly less active but he is never very active anyway. I have 4 guppies in a 10 gallon tank, he is the only one showing any signs of whatever this is, the others are fine. He doesn't get picked on as far as I see. Two mystery snails in the tank also, seem fine. I have had these guppies for about two months and this just started. I have been having algae growth recently, could cleaning that help him? I will try to attach the best picture I could get here, his body by his tail did not have ANY red before. Does anyone recognize this? It almost reminds me of a bruise. How can I help him? Are my other guppies in danger? Tank information: 10 gal Ammonia: 0 Nitrite: 0 Nitrate: 5 pH: 6.8 Did a 30% change yesterday. 4 guppies and two mystery snails.

Colu Posted March 8, 2021 Share Posted March 8, 2021 (edited) It looks like a bacterial infection I would treat with maracyn if maracyn doesn't work try maracyn2 as it could be a gram negative bacterial infection @Nicclem Edited March 8, 2021 by Colu Link to comment Share on other sites More sharing options...
Nicclem Posted March 8, 2021 Author Share Posted March 8, 2021 @Colu Thank you!! I cannot find anything like this online. If this is a bacterial infection, do you know what kind? It is not easy for me to drop $20 on a medicine right now that might not work so I just want to be sure. Link to comment Share on other sites More sharing options...
Colu Posted March 8, 2021 Share Posted March 8, 2021 It difficult to tell what type of bacterial infection it is that is whey I would treat with maracyn if that doesn't work maracyn2 Link to comment Share on other sites More sharing options...
Nicclem Posted March 10, 2021 Author Share Posted March 10, 2021 @Colu Thanks again for trying to help, the guppy passed this morning. He looked bloated when I found him but last night he was acting normal. I just hope whatever this is doesn't spread to the others! 1 Link to comment Share on other sites More sharing options...
Colu Posted March 10, 2021 Share Posted March 10, 2021 (edited) Sorry to hear he didn't make it I would give the other fish Couse of maracyn as procautionary treatment to cover all bases Edited March 10, 2021 by Colu Link to comment Share on other sites More sharing options...
