They lok small now but your 125 gal and my 150 are just drops in a bucket for these fish.
So this is my guess here the jd and gt are gonna grow slow. As the others have said the lyonsi may grow like a weed. Know nothing about the polleni
Lol if these were my fish it would play out like this....lyonsi claims tanks harrasses smaller fish, smaller fish grow even slower because of stress and maybe the lyonsi turns out be be an aggressive eater, smaller fish dont get there share.....jaws has to rehome MORE fish lol
