I was having a conversation with cichlidnut about where I can fit tanks that aren't over the top. He pointed out I might be able to fit some in my 60 gallon tank's stand! I immediately began searching for dimensions and found that 10 gallon tanks are a tad too large. This means I'll be doing 2x 5.5 gallons and would like input from you all!! Tank 1: He insists I do one RCS tank, and I do think shrimp are neat so I'll be exploring this option. I guess my questions are as followed:What kind of plants?What kind of substrate?How many RCS for a 5.5 gallon to start?What would be the point where I should start finding homes when they breed?Anything else you think I might need to know about RCS! Tank 2: This one is open for popular vote! I was thinking maybe a betta, but I'm not sure I'd be okay with anything less than a 10 gallon for one. Thanks! I'll be sure to post pictures when the tanks are done!
