Love the amount of thought and effort. However, this hap-hazard method is riddled with future problems. Keeping living creatures hidden in a drawer, only seeing daylight a feeding or when you fancy a peek seems unfair. The fish deserve to see you too! Why keep so many? Surley a gold fish bowl...
considering you like the oddball fish (elephants) etc i would highly recommend the reasonably hardy "Polypterus ornatipinnis" or ornate birchir. Very colourful if you get a decent supplier and not too expensive. Great character too.
I'd also consider keeping the angel display tank you were...
