Do Dats need Dithers?

That's a pretty good number of clown loaches as dither fish. And yeah, I believe the tank is pretty overstocked.. 120 gallon just ain't gonna do it, if you ask me, because those guys get huge over time when fed properly, also when there's good water conditions provided and good space.. and so do your indo dats will get very very large as well. The tank could be used as a grow-up tank though until they get big enough.. then one day, you can upgrade.. So technically you can actually keep them in the tank for now, if they are small-medium size not monster size. I think you would need at least like a good 250 gallon like mine to house them or even better, larger size. |

Good luck man.

You're welcome glad I could help out, cheers
