A couple of weeks since my last update and all is going well in this tank. I cleaned the other FX6 filter last week and tested the next day and my parameters were as follows:
Temp 26.0
Nitrate- 3-5ppm
Nitrite - 0ppm
Ammonia - 0ppm
PH - 7.6
I am pleased to get the nitrates down so low so thank you to all of you that commented, much appreciated. My filter cleaning regime will be to clean each filter once every two months but staggered, so effectively cleaning one of the two filters every month. I’ll keep testing as the group grow to ensure I am managing those nitrate levels effectively. I am definitely in finding the Sallifert test easier to get a clear indication of ppm and the low level scale is really useful.
I haven’t really talked much about the actual fish yet aside from posting the photos and videos. They are really confident and will always come to the front of the tank when I am there, they also take food out of my hand. Generally they are all getting on well, I have seen no evidence of any aggression between the different species but conspecific aggression is obvious particularly after feeding. The Thorichthys Meeki regularly posture to one another and occasionally lock lips .Due to them all looking quite similar at this stage it is hard to differentiate between them to see if there are more dominant ones in the group or which are male or female but despite the occasional aggression none of the Meeki have any damage or appear stressed.
The Hypsophrys Nicaraguensis are coming along well, no bright colours are developing yet but this was normal with the last two females I kept who didn’t show their gold and blue color until 2.5-3 inches. No idea on sex but I do have one who is larger then all the others so I’m guessing could be a male, we shall see. Great personality fish, very interesting to watch and not much aggression other than the flaring of gills amongst themselves. Still very small though.
The group of Thorichthys Maculipinnis are probably showing the most progress particularly the two dominant fish. I had what looked like two dominant males and a dominant female. I think I have 2 females due to them displaying a black spot on the dorsal fin and believe the rest are male however one I am not sure on. The female would keep to one side of the tank and the two males would squabble over the rest and I never really saw them interact with any of the females aside from a bit of chasing here and there after food.
Since I completed the filter clean and a big water change approx 60%, the largest male and the largest female have been spending much more time together and have been showing signs of a pair bond. No real breeding signs yet as they are still immature but a definite change in behaviour and their colors are really starting to develop. Here is a photo of the two of them together and I’ll post a video as well. Let me know what you guys think.
Thanks again
