And my sewellia's:
What I want to do is the following: take out all plants and put in extra kilos of these blue/black rocks. Replace the plant substrate with all sand and add extra flow (so I maybe an breed some Sewellia). The filter in there now is only 280 L/h (60 gph) and I was thinking about adding a flowpump of about 1200 L/h (260 gph) or replacing the current filter with a Fluval U4 of 1000L/h (220gph).
Any advice on that part?
Second advice I'm looking for is whether that much flow isn't going to be a problem for my Tanichthys micagemmae. If it is, I also have a 400L (90G) planted tank where they can live on in. Any advice on the fish would be welcome as well!
If you got a longer, low tank such as a 20 gallon long (30" x 12" x 12" or 75cm x 30cm x 30cm = about 68 liters) you could aim the power head along the front, and put the intake at the other end, but still at the front, and have pretty good flow there, and rocks and gravel with only tiny plants (if any) between the rocks like any rushing stream. It is the shape of the tank rather than the actual volume.
Toward the back, especially at the back corners there would be less water movement and perhaps you could split your tall plants, maybe add some driftwood to make it look like the roots of trees coming down the bank. That might make it calm enough for the Tanichthys. Maybe not, though, so hang onto the current tank and set up for them, just in case.
Happy fish keeping!
I know how to sex them and all the others are definitely females, but this one I'm not sure. Looks like a female to me, but he/she is so dominant that it could be a male as well. Who knows whether it is a male or female?
