Again, the advantage this time is there will be more room to work with so I'll be able to provide a plethora of hiding spots. Having spent most of their lives sharing one cave it'll be interesting to see what happens when they're spoiled for choice. Not to mention they're all either adults to subadults (one's easily over a decade old, another's about 5-6 years and the remaining two are at least a couple years old) and have never had a problem with anybody that isn't "snack sized."The bigger clowns get, the less tolerant of other fish which impinge on where the clowns want to be. I have a number of various sized caves and other forms of shelter where they can hide and feel safe. My big guys will not tolerate a pleco deciding to live in their hiding place. The clowns began acting this way as they got into the 6 inch or more range TL. I did find a couple of pleco head and spine bones with no meat on them and piles of scales or else nothing at all. Maybe the fact that these were ablbino bn made them more of a target?
I tend to try to maintain somewhat similar fish in tanks relative to where they live in the wild. I try not to mix Africans, SA, Asian etc. I may be a little lose with species from the same continent but not all that close within that continent. When my clowns were smaller in the 75 gal., I had them with 65 cardinal tetras. I would not try that today given how big the clowns are now.
i would give the loaches away as they get far too big even for a 125 gallon imo. I would give away the rainbows, the rainbow shark and those UDC as well as the danio where they need a group of 6 or more. However I am mixed on the pleco. What gender is this one and the other one?To give full info the 55 residents are 4 clown loaches, 2 Australian rainbow fish, 1 giant danio, 2 upside down catfish, 1 rainbow shark and 1 bristlenose pleco.
