Long story short. I have a 27g cube. It was stocked with mostly danios. Two different varieties from two different sources. I've come to the conclusion that my danios are one by one dropping from the 'curved spine' danio genetic issue. No other clues to sickness.... just becoming lathargic, not eating, and swimming with a droopy tail. None of the other stock in this tank have issues. Danio-wise, I now have 4 glo danios and 1 long fin silver danio left. I started with 6 glos and 7 longs. So. I have no intentions of getting more danios. I was going to try purple passions. I thought maybe a different strain of danio would help, but I'm slowly becoming more irritated with the danio genetics. This being said... I'm looking for suggestions of what to stock in a 27g. This tank is fantasy castle themed. It has a cave, real rock decorations, and a bubble bar. I have some real plants but some fakies in there also. The fakie stuff is brightly colored blues and purples. So I'm thinking bright colored fish would look nice with this. This tank also gets a wc every week, about 30% - 40%. Here is the current stock: 4 panda cories (school to be brought up to 8 very shortly) 1 sunset golden gourami (female) 5 danios (probably temporarily) Regardless of what happens to the danios, the pandas and gourami are staying. Thoughts on new stock going into the future? Should I wait out the danio demise before moving forward?
