TOtrees Posted January 20 Share Posted January 20 Posting this here as a community service of sorts. At least I hope it's rec'd that way. In a couple different threads lately I've written how important the size of the food you feed can be when you have multiple species in a tank. Whether it's a community tank with "shy guys" on the floor (cories, kuhlis, etc), or greedy eaters at the top-middle, or a grow-out tank with multiple species where you want to ensure everyone gets enough. My comment/suggestion has been that you can use the physiology and behavior of your fish to your advantage by choosing tiny foods for the top-feeders and bigger foods for the bottom dwellers. Duh, right? Well I had a great opportunity to record this in a couple of my 10gal grow outs that both have a mix of guppies and gold ocellatus shell dwellers. Just before I took the vids, I fed 200-300 micron golden pearls on the surface, and the guppies are all staying up top and are totally focused on that (this food floats when sprinkled up top), and I fed a sinking micro-pellet food at the same time (similar to crumbled bug bites community), which the ocellatus happily eat on the bottom. The pellet food was introduced below the surface, so it sank right away, and the guppies pretty much ignored it because the floating/smaller GP is more to their liking. This partly works because of mouth size also - ocellatus have cavernous maws, while guppies have relatively smaller mouths. You can see this in two separate tanks here, both with the same species mix just different sizes. With apologies for the glare, here is the older group, you can see the guppies at the top eating the last of the GP, and the golds at the bottom scrounging the pellets. Here are a couple yt links: The older group (same tank as above): https://youtube.com/shorts/PVnCquoo_AI The younger group: https://youtube.com/shorts/IpQzYhcFm_4 (shout-out to Star Wars fans re the AT-AT - best ornament ever) In both vids, with few exceptions you can really see the guppies staying up top (even though most of the floating food is gone) and not bothering the golds on the floor. Most folks consider guppies to be little piggies, and if a single food type had been introduced (whether it was the floating gp or the sinking pellets) I think we can agree there would have been less available for the golds. Distracting the guppies with the floating food ensures the golds get enough on the floor, and get time to eat it. What about something like cherry shrimp or cory fry (slower eaters than the golds)? In that case I would have again gone with a floating top food, paired with an even larger bottom pellet (like the vibra bites large size). Any similar stories/experiences out there? 2 Link to comment Share on other sites More sharing options...
