So my plan is to get the loaches next month and quarantine them, which will most likely take me 2+ months to add them into the main tank. Probably get them at the end of October to make my tank more established. I was thinking about getting 6 or 9 loaches since I'm paranoid I might overstock the tank. Almost done with selling my breeding stock and eggs so will only have the loach display tank and a very long break from breeding anything
.
Anyways some questions:
How much hillstream loaches can I put in the tank (20 gallon long)? I'm planning on getting only the loaches that grow to 2 inches. I like being a little understock in my tanks.
What plants can I add? Plants I have right now: moss, ferns, crypts, vals, anubias, and anacharis (I know it sucks up nutrients that algae need to grow). I plan to take out the anacharis and moss since the filter and powerhead pushes it everywhere. I know fast current flow is not ideal for plants but would love to add plants even though the plants are not found in their natural habitat.
What's the ideal temperature for them? I have my heater set to 68F right now but might bump it to 70F. A lot of forums I've read have upper 70s to 80s. I think that's a little too hot for them.
Is 2 powerheads too much for the tank? One is a 158 GPH powerhead. Also, this tank will only contain the loaches, no other fish.
