If you have read my threads in other forums, you'll know I am currently beating back some algae, recently upgraded my lighting, and will soon add DIY CO2. I never did water testing, but intend to start - at least with nitrates and phosphates. Will go on a shopping trip this weekend.
My short term plans are to get my plants as healthy as possible. But I'm wondering if my long term plans could involve adding more fish.
I understand that the 1" per gal is only a rough guideline. What other factors should I consider in determining fish holding capacity? What water parameters should I consider in determining whether my bioload is maxed out, and what parameters should I consider in determining particular species to add?
I have a 30gal with 55W AH retrofit, bio-wheel filter, 76 degrees, approx 12 hr photoperiod. Moderately planted at present, due to radical trimming to control algae. Should fill in to be moderately to heavily planted.
anubias - nana, congensis, frazerii
crypt wendtii bronze
1.5" albino bristlenose pleco ("Old Yeller")
6 red-eye tetra
6 serpae tetra
8 glow-lite tetra
A while back I got rid of my common plec as he was getting too big. I replaced him with the bristle, and increased the sizes of my tetra schools. Everyone looks happy and healthy now, but I'm not thrilled with the way the tank looks. Specifically, I think it would look nicer with a couple of larger fish to balance all the the tetras. And the majority of the action is going on in the bottom 2/3 of my tank.
I know Old Yeller is gonna get bigger. But I think my tetras cories, and otos are pretty light in terms of the bioload they add. Moreover, I think when my plants get healthy they will help support a fish population on the high side.
What do you think?
If you think I could add something, what do you recommend? I was thinking of maybe 2-3 dwarf guorami, a small school of buenos aires tetras, or a couple of giant danios. Or maybe some hatchetfish hanging out on top. I really like the looks of blue rams, but my understanding is that they are somewhat picky in their water/temp preferences.
I'll let you know as soon as I get any results on my tank and tap H2O.
