Adjusted substrate for the heterospila

  • We are currently upgrading MFK. thanks! -neo
If you have a large tank and can duplicate the natural habit that is awesome, i just think for the regular hobbyist doing WC and vacuuming the gravel/sand it is just to time consuming you have to get down in between all those crevices

And I'm telling you, it's not.

I think it looks great. I did a similar thing in my 75, mixing different colored gravels and dispersing it across the surface of sand. Brought out the best colors in my male convict. It’s really not all that difficult to siphon up debris either.

if there is one very small negative it’s that over time, with digging and everything, the gravel tends to get covered up with sand. That’s just my experience though and nothing another bag of gravel can’t fix.

I posted not long ago that I'd moved the heterospila and juvenile marbled fenestratus from the 8ft, 135gal to the 6ft, 135gal and taken the opportunity to change the substrate. The 8ft tank had a mix of black and natural brown gravel which the fish looked fantastic over - coloured up just right, not too dark and not too light - but I hated the look of. Wanted to switch to a more natural sand, but after failing to find a dark natural colour I liked, I used Caribsea "Crystal River" which was really light and did exactly what I was afraid of - washed the fish right the hell out. So then I had to brain storm and search for a solution, preferably something I could add to the existing sand as I didn't want to have to haul it all out again. Finally decided on this mix - adding Marina natural beach pebble (larger stones) and Marina natural gravel (regular sized aquarium gravel) to the sand for a darker, but more natural look. Has only been a couple of days so the fish are PO'd and hiding from me - hence the empty looking tank lol - but it looks much better and already the colours on the fish are darkening up as they were before. I'm still getting used to it, but I think I'm happy with it at this point.

First photo is the before, with just the sand that washed them out, and then with the rock addition.

Looks great. That's the approach I used with the 125. Mixing substrates adds texture and depth!
 
Congrats ! The tank looks great very appealing. I almost want to do the same and add some pebbles for character to my tank over the sand
