gmerek2 March 28, 2023 Share March 28, 2023 I need some pods to re seed my tank I want to borrow a rock from your tank for a few hours or 24hrs. Willing to drive if tank or refuge Is loaded. Those giant cockroach looking ones are what I need. My mandarin is 5 years old but losing a little weight. I let my tank go hypo, lost the large ones but the small are still there. Thanks!

flooddc March 28, 2023 Share March 28, 2023 Welcome back stranger! I can spare a rock or two from my sump. Link to comment Share on other sites More sharing options...
DaJMasta March 28, 2023 Share March 28, 2023 (edited) A way to boost copepod growth in your system is to feed phytoplankton, live or concentrate, or even fine particulate foods. Even modest daily doses can make a notable improvement. If your tank is 5+ years old there are likely several species already in the nooks and crannies, so the goal should be less about introducing more (not that it can't help, but that it's probably not the issue) and more about growing the population you currently have (more food, more places to hide without predators, etc.) Edited March 28, 2023 by DaJMasta Link to comment Share on other sites More sharing options...
lynn.reef.nerd March 28, 2023 Share March 28, 2023 The large cockroach ones are amphipods? Link to comment Share on other sites More sharing options...
YHSublime March 28, 2023 Share March 28, 2023 You probably have folks closer, but I've got rocks for you if you need. Link to comment Share on other sites More sharing options...
gmerek2 March 29, 2023 Author Share March 29, 2023 Lynn the ones that scurry off real fast when you pull algae out or flick the lights on. Curious what they are Link to comment Share on other sites More sharing options...
DaJMasta March 29, 2023 Share March 29, 2023 Amphipods are probably right. Good meals for mandarins and the like, so the populations will probably be in the sump. Rock rubble could make a good habitat, as would a chunk of macroalgae. Link to comment Share on other sites More sharing options...

The salinity dropped and killed all of them. I have a no fish 75g sump loaded full of rock and algae. Link to comment Share on other sites More sharing options...
DaJMasta March 31, 2023 Share March 31, 2023 Well then seeding is a good option, for sure. A few places sell them, but basically any chunk of rock or macro from an active system should have a few, and I'd expect pretty good colonization inside of a month even with just a few introduced.
