hi guys and girls
I have a 72g tank heavily planted tank. I have 30 or so rcs. 5 corys, and about 24 fish (neons, glowlights, rasboras, embers).
I really love the look of the pacific blue eyed rainbow (Pseudomugil signifer). I am a bit worried about the size of the adults. I know they may/will snack on some babies.
Has anyone kept them with shrimp without loosing their entire population? Or am I just asking for a masacre.
Absolutely. Just continue with regular weekly water changes. No need to alter the routine, or as Simon said, add additional water changes to the routine.
Unfortunately, as long as you are using tap water, the lowest pH it will get is what you have from the tap. 7.4/7.6 as you mentioned above.
If it gets down to 7.4, that should make a difference to the shrimp. Especially if GH is around 4.
