Hello! I'm new to Fishlore but I've been researching on this site for a long time. I just bought a 10 gal and made sure it didn't leak - now I'm researching the best stocking choices. So far we have made a few decisions about the tank (my friend and I are running it together, since he got me into fish) I can't go above 10 gal (which sucks because I wanted to start at 30. . .) because my university doesn't allow more gallons. . . but we're making do with a 10 gal in terms of stocking. (and frequent water changes aren't an issue! we're willing to put as much time in as possible) Decisions so far: It's going to be a so-so blackwater tank. So-so because the fish aren't all indigenous to the same region. I did make sure that I chose species that all favor the same conditions - low current, subdued lighting, soft water with acidic - neutral pH. Basically blackwater conditions. The plants will be mostly native plants as well, and I'm a huge aqua-sculpting buff so it will be heavily planted. Lighting: I'm going to do a pretty dim light throughout the tank, but I want to create some spotlights that shine on specific areas where there can be denser plant-life. This way I can grow a little forest of plants and keep the overall lighting subdued. Substrate: I'm doing very fine sand over this volcano rich rainforest substrate for the plants. I'm trying to find dark sand if possible Filters: I haven't looked into specific filters yet so any recommendations are appreciated! (sorry I know this is a lot, but my friend and I are pretty obsessive and we want to be thorough) Stocking choices: So far we have decided on 4-5 cory habrosus/dainty cories (i love cories so much) and 2 peacock gudgeons (my friend insists on these). I have heard that gudgeons do better in a m/f pair so that's why we're doing two They're both bottom dwellers but I've researched and have heard that people can keep them together without an issue (obviously the tank will have a lid so jumping won't be a problem) But we wanted something in the top/middle of the water level so the tank doesn't look too messy We've come up with either 3-4 clown killifish or 3 sparkling gourami. (which we heard do best in trios) Add 2 amano shrimp to this, since peacocks eat dwarf shrimp; and 1 or 2 nerite snails, and that's the stocking we're looking at. For either killifish or sparkling gourami, aq advisor says we're overstocked - I know that site isn't reliable but i was wondering if it would still be possible to do either species, if we need to move numbers around, or if there is a better rec. for top dwellers that don't need large schools. (we were going to do endlers but apparently they're hard water fish so that was thrown out) ((also i'm pretty sure its impossible since theyre huge waste producers, but would it at all be possible to house one mystery snail instead of a nerite?)) Sorry for the long post, and thank you for any advice or suggestions!
