Thanks for your reply Finwin (Sorry don't know your actual name!)
I like that backup plan. I will start looking for them, double the layer due to heavy weight.
However, At least for few months, they should be fine with separation, the mesh is really snug tight, I checked and moreover, my wife certified it! Hahahaa. She added that we will separate both our kids, a 6 years old girl and 2 years old boy, if they fight like these two guys do! Hahahhaha.. She kind of likes the idea.
The suction with the ties are enough until these guys can use their full power in adulthood..
Please see pictures. Mango is really turning well, color and personality wise, he is growing a lot.
Your tips about sprinkle of orange gravel, and background are nice. Yet, store ran out of orange gravel, I will need few more bags of gravel, same color, same kind!
In that old school filter, I added, extra, fluval bio-rings, I like fluval products, I used 220 external filter in 29 gallons tank, and it was so powerful canister, I had to give up everything during my 1.5 years assignment back in my native! Miss that setup, and my baby FH Tintu (In my profile picture)... He was 2 inches when I got him, grew 4.5+ with big head and super pearls in two years!!
Anyway, my question was, I did a mistake that I didn't rinse bio media (fluval U max BioMax underwater) media before adding to that old school filter, and now water seems cloudy. I don't want to interrupt bacteria cycle, and waiting for water to clean up! I added the media since yesterday.. hope that water cleans up soon. I also added sponge, some aqua flo product, fine grade, in my HOB filter, with existing media are zeolite amonia Marinland, and fluval sponge, with some poly fiber (poly fill) in HOB...
Please advise. I yet to plan on plants, but the space is constraints... I already occupied my daughter study table, yet, she got space for homework, and toy stand! She participates in fish keeping hobby so she gave up some space easily...
