After having read these posts, I want to run my idea past you all about setting up a tank for just firebellies...Set up to have glass partitions siliconed to bottom and sides for fresh water area about 5" deep with filter sectioned off in one back corner...and pump for small waterfall area in opposite back corner..glass to be slightly lower for better water movement...and a return from one corner to the other as a small siliconed, rock stream on rubber pond liner material...the water area for guppies which firebellies can eat, and water for them to do their thing..with tinted glass against the planted area...36 G L tank..live plants, screen top. Any suggestions, comments, etc.? I want to plan carefully to have it work the FIRST time...One of my other tanks is set up as a paladarium and has Endlers in the water portion...no filter so I just do small water changes every week...the female had babies last week..
