Okay so I have a 29 gallon tank. 2 paradise gouramis, 5 neon tetra, 3 long fin serpe tetra, 2 mystery snails, and 3 kuhli loaches. I mean I'm pretty sure I've hit my limit on fish so hard not to get just one more. I have 2 30 gal hob
filters, a lot of plants, a 2.5 gal
filter (just use it for water flow) and a DIY co2
system (I don't use it all the time though).
