So I am just establishing a quarantine tank, getting it through a fishless cycle right now. I was given some water and gravel from a fully cycled tank to try and help, but I still need the bio wheel in the quarantine tank to get the bacteria established. My main tank just finished dealing with ich, I will still be feeding the medicated fish food for another three weeks or so and should not probably add fish to it until then. What I really need to add to my main tank is something to eat the algae which is starting to grow. Something to nose its way through the substrate as a bottom feeder would also be good. I have looked at a number of different possibilities, but we have not come to any decision yet on what to add. So I am supposed to quarantine the new fish for 2 to 4 weeks depending on who I asked to be sure that their healthy before adding them to the main tank, but the quarantine tank does not have algae and only has a very small amount of gravel substrate. So what will these fish, so desperately needed in the main tank, eat while there quarantined? The main tank is my 155 gallon planted bowfront. It has had fish in it for just over three weeks at this point, and there is not a lot of algae, but I can certainly see some algae on the leaves of a few of the plants and on the nooks and crannies of some of the equipment in there. It currently has rainbow fish and gold barbs, suggestions for bottom feeders and algae eaters would also be welcome!
