Aye the second is a Fluval Edge with only led upgrades, light doesn't reach the edges of the tank lol.
1st pic:
75 Gal
MTS with black sand cap
plants from left to right are crypts: spiralis, wendtii, parva and some other one I don't know, dwarf chain sword in the middle red ludwigia, a sword in the back right behind the DW (something with fire in the name but I forget what it was) and scattered flame moss. There are a few potted plants I threw in there because I changed my mind and don't know what to do with atm.
As far as fauna, well I'm a little all over the place which is kinda bad and I'm overstocked. Don't lecture me!
There is some type of synodontis (longirostris? maybe) ~8", another that is smaller, ~5" that I got for free which they called an african featherfin, two or three upside down catfish and many corys: sterbai, paleatus, metae, albino, panda? and three line/julii, giant danios, an angel, a honey gourami, german blue and gold rams, a few apistogrammas, two bristlenose plecos, some random platys I saved from being flushed, a few assassin snails and nerites, about a dozen or so otos and for the moment two small tiger oscars I'm housing temporarily. I haven't seen very much aggression towards my other fish from the oscars since I've been trying to keep everyone well fed.
equipment
I've got a fluval 405 and a rena xp2 both rigged up in there with a random powerhead I had and an aqueon circulation pump rated I think like 450-500 gph
for lighting theres just a hagen single t5ho on top with one of their life glo bulbs I found super cheap for like $5-6
I do have a paintball co2 system in there too but I don't run it anymore, plants seem to do fine except I get a bit of algae here and there, doesn't bother me though.
2nd pic
fluval edge 6.6 gal with mr11? led upgraded lights and the stock filter it came with.
again MTS capped with black sand and theres parva and an anubias and also a bunch of random algae growing on both of the pieces of DW. I actually like it though it looks pretty cool IMO. Thats the green you see growing off the top and sides of the DW.
There are many rcs that are breeding, a single oto who I feel bad for and haven't gotten around to moving him back into the 75, also a single SA bumblebee catfish I plan on moving over to a different 12 gal I've recently set up to house a bully of a red tailed shark temporarily and about 4 dozen assassin snails that keep breeding and many many many trumpet snails they keep eating which explains all the little empty shells everywhere you can sorta see in the picture.
