I've got my 2.5g minibow set up with a dozen or so guppy fry in it. It's got the filter running (with a sponge over the intake), but how do I go about a water change with out sucking up or scooping out the fry?
+1 Though I never used nylon cause I wanted to get all the debris out. You have to move very slowly. Once the water currents pick up...it'll take forever for the debris to settle down again.You can also use a clear turkey baster to get out debris. Works great and you can see if you scoop up fry. Or you can put a old nylon over the airtube too...
