I am putting together a 40 gallon breeder divided tank (not for breeding just the best tank I could find at Petco $1 per gallon sale) Today I was wondering if there is a bottom feeder that has a lower bio load that I could put in the tank and rotate from divider to divider to assist with keeping the tank clean. I am pretty open to anything. Any suggestions?
I will put 6-8 Betta fish in the 36x18x16 tank. Please let me know how many of whatever you suggest would be ok.
Also I plan to have a few sponge filters in the tank (I have 6 I need to find how much is needed) and I also have an 2 aquatech filters I was going install only one since I have sponge filters. There will plenty of cover available but most of it will be in silks, ornament and the rest in low light live plants.
